A 1.5-inch rise sits in an awkward middle ground. It’s tall enough to catch a wheelchair caster, a walker’s front wheels or a toe, and it’s well above what most robot vacuums can climb, but it’s too small to justify a full modular ramp. A solid rubber threshold ramp built for exactly 1.5 inches solves it, as long as you match two numbers: the rise, so the top edge sits flush with your sill, and the depth, which sets how steep the climb feels. Below, we compare three rubber ramps by exact rise, usable width, slope ratio and published weight rating.

Detailed Reviews: 3 Rubber Ramps Built for a 1.5-Inch Rise
Every review lists the slope ratio, because that’s what decides how hard a ramp is to roll up. Divide the ramp’s depth by its rise: an 18-inch-deep ramp on a 1.5-inch rise is 18 ÷ 1.5 = 1:12, the maximum running slope the ADA Standards allow for accessible ramps. The bigger the second number, the gentler the climb.
1. EZ-ACCESS TRANSITIONS Angled Entry Mat (1.5″): Best Overall
EZ-ACCESS TRANSITIONS Angled Entry Mat (1.5-Inch Rise)
Good fit if: You want a ramp you can anchor down, a side approach on a narrow stoop, and the option to trim it for a slightly lower sill.
Watch out: At about 1:9.3 it’s steeper than the 1:12 SafePath, so it takes more push in a manual chair.
Check Price on AmazonExact Specifications
- Rise: 1-1/2″
- Depth: 14″ (about 1:9.3, roughly 6.1°)
- Overall width: 39-7/8″
- Usable width: 36-1/16″
- Weight capacity: 850 lbs
- Material: recycled rubber, about 18 lbs
- Edges: beveled left and right sides; the edge that meets the threshold is square; the front tapers to about 1/8″
- Install: anchoring hardware included for wood or concrete
- Warranty: lifetime (per EZ-ACCESS)
Why It Fits
The 36-inch usable width covers a standard 36-inch exterior door, and the beveled sides let a wheelchair or walker roll on at an angle when there isn’t room to line up straight with the door. EZ-ACCESS also includes anchoring hardware, which matters on a doorway: a ramp that creeps away from the sill leaves a gap that wheels and toes catch on.
The bigger advantage is the size range. EZ-ACCESS makes this mat from 1/2″ to 2-1/2″ in quarter-inch steps, and says it can be trimmed to reduce height. If your threshold measures 1-1/4″ or 1-3/4″ rather than a true 1-1/2″, you can order that exact size instead of settling for close.
What to Watch Out For
- Steeper than the SafePath. At 14 inches deep, the slope is about 1:9.3. That’s fine for walkers, power chairs, carts and robot vacuums, but someone self-propelling a manual wheelchair will notice the extra effort compared with a 1:12 ramp.
- Narrow doors need trimming. The 36-1/16″ usable width is wider than a 30″ or 32″ interior door opening, so plan to trim it or check how it sits against the door casing.
- New rubber smell. Recycled rubber can smell strongly when new. Airing it out in a garage or on a covered porch for a few days before indoor use helps.
2. SafePath Products EZ Edge 1.5″ Rubber Threshold Ramp: Gentlest Slope (1:12)
SafePath Products EZ Edge Threshold Ramp (1.5-Inch Rise)
Good fit if: Someone will roll over it in a manual wheelchair on their own, or you have a 36″ door or a 72″ double door.
Watch out: Adhesive is sold separately, and the seller doesn’t publish a numeric weight rating.
Check Price on AmazonExact Specifications
- Rise: 1-1/2″
- Depth: 18″ (1:12, about 4.8°)
- Widths: 45-3/4″ (model MRAEZ1310, sized for a 36″ door) or 81-1/4″ (MRAEZ1340, for a 72″ double door)
- Weight capacity: listed as “no load limitations” (no numeric rating published)
- Material: 100% recycled rubber, UV resistant, made in the USA
- Install: no tools needed; can be adhered temporarily or permanently to concrete, asphalt, wood, tile or marble (adhesive sold separately)
- Warranty: 10 years (per the seller)
Why It Fits
At 18 inches deep, this is the only ramp in this guide that hits a full 1:12 slope on a 1.5-inch rise. That’s the easiest climb here for anyone pushing a manual wheelchair without help, and it gives the most gradual transition for walkers and rollators.
The two widths cover the doors most homes have: the 45-3/4″ version spans a standard 36-inch door with room to spare, and the 81-1/4″ version covers a 72-inch double door or wide patio entry in one piece, with no seam for a caster to drop into.
What to Watch Out For
- Confirm the listing dimensions. One retailer page lists this ramp as 1-1/2″ H x 18″ D in its spec table but mentions “1 1/4″ H and 12 1/4″ deep” elsewhere. Check the exact height and depth on the listing you buy from before ordering.
- No published load number. “No load limitations” isn’t a rating you can compare. Solid rubber ramps carry most home loads easily, but if you need a documented capacity for a heavy power chair, the EZ-ACCESS (850 lbs) states one.
- Takes floor space. 18 inches of depth plus 45-3/4″ of width is a large footprint inside a doorway or tight hallway.
3. VEVOR 1.5″ Solid Rubber Threshold Ramp: Best for Heavy Loads
VEVOR Rubber Threshold Ramp (1.5-Inch Rise)
Good fit if: You roll carts, hand trucks, mowers or a loaded dolly through a garage or utility door and want one wide, heavy-duty piece.
Watch out: At about 1:8.4 it’s the steepest ramp here, so it’s the hardest climb in a manual wheelchair.
Check Price on AmazonExact Specifications
- Rise: 1.5″ (3.8 cm)
- Approach depth: 12.6″ (about 1:8.4, roughly 6.8°)
- Width: 43.3″ (listed as 43.3″ L x 12.6″ W x 1.5″ H)
- Load capacity: 33,069 lbs (15 tons), as claimed by VEVOR
- Material: solid rubber with a non-slip textured surface and beveled edges, about 22 lbs
- Extras: one channel underneath for running a cable
- Install: no tools or anchoring required, per VEVOR
Why It Fits
VEVOR markets this ramp for curbs, garages and doorways, and it’s built like it: a single 43.3-inch-wide slab that covers a 36-inch door with overlap on both sides and carries a vehicle-grade load claim. For a garage-to-house door where carts, hand trucks and wheeled bins cross every day, that width and mass are an advantage.
The underside cable channel is a small but useful detail if you need to run an extension cord or low-voltage line across the threshold without lifting the ramp.
What to Watch Out For
- The steepest slope here. 12.6 inches of depth on a 1.5-inch rise is about 1:8.4. It’s fine for powered and pushed loads, but for independent manual wheelchair use the 1:12 SafePath is the better match.
- Read the load claim for what it is. 33,069 lbs is a vehicle-style rating for the rubber itself. It tells you the ramp won’t crush; it says nothing about how stable a wheelchair feels on it.
- Too wide for some doors. At 43.3 inches, it’s much wider than a 30″ or 32″ interior door, and the listing doesn’t mention cut lines for trimming.
Robot Vacuum (Roomba/Roborock) Climb Check on a 1.5-Inch Lip
If you’re buying a ramp so a robot vacuum can reach the next room, the math is blunt: 1.5 inches is 3.8 cm, and that’s taller than almost any robot vacuum is rated to climb on its own.
- Mainstream models: most robot vacuums handle thresholds of about 1.5 to 2 cm (0.6 to 0.8 inches). Roomba i3, i7 and s9+ models are commonly cited at 1.8 to 2.0 cm, and Roborock S7 and S8 models at up to about 2.2 cm.
- Newer climbing models: Roborock’s lift-chassis robots go higher. Roborock rates the Saros 10 at up to 3 cm on a single threshold, and in one independent test a Qrevo Curv crossed 28 mm thresholds but could not cross a 41 mm one.
- Bottom line: no mainstream robot is rated to climb a single 3.8 cm lip. A ramp is the fix.
Why a steep ramp can fail
- Bumper hits: a robot’s front bumper sits low. If the ramp’s leading edge or face is too steep or too tall, the bumper presses before the wheels start climbing, and the robot treats the ramp as a wall and turns away.
- Cliff sensors: robots use downward-facing infrared sensors to avoid stairs. Very dark surfaces reflect little infrared light, so some robots read black rubber as a drop and refuse to drive onto it.
- Getting high-centered: a short, steep ramp can leave the robot balanced on its belly at the crest, with its drive wheels spinning in the air.
Which slope works
Gentle is the goal. Dreame’s own support guidance suggests keeping a robot-vacuum ramp at or below about 12°. All three ramps above fall well under that: about 4.8° (SafePath), 6.1° (EZ-ACCESS) and 6.8° (VEVOR). Two more details matter as much as the angle: a thin leading edge the wheels can roll onto (the EZ-ACCESS tapers to about 1/8″), and a ramp on both sides of the threshold if the floor drops on the far side too. If your robot still refuses a black ramp, clean its cliff sensors, then check your app for a dark-floor or carpet setting before assuming the ramp is the problem.
How to Measure a 1.5-Inch Rise Before You Buy
- Measure the rise on each side. Set a tape measure on the lower floor and measure straight up to the top edge of the threshold. Repeat on the other side; interior and exterior heights often differ.
- Measure the usable width. Measure the clear opening inside the door jamb, jamb to jamb, with the door fully open.
- Check the depth you have. Measure how much floor in front of the threshold is clear of rugs, door swings and steps. A 1:12 ramp on a 1.5-inch rise needs 18 inches.
- Apply the quarter-inch rule. If your rise measures between 1-1/4″ and 1-3/4″, a 1.5-inch ramp is the right height. Under 1-1/4″, look at a 1″ or 1.25″ ramp so the ramp’s top lip doesn’t sit above the sill.
Measuring closer to 1-3/4″ to 2″? A 1.5-inch ramp will leave a small step at the top. See our guide to the best rubber threshold ramps for a 2-inch rise instead.
FAQs
Is a 1:8 slope OK for a wheelchair?
For short threshold ramps, 1:8 is common and usually manageable for power chairs, scooters and caregiver-pushed chairs. For someone pushing a manual wheelchair alone, a gentler 1:12 slope is noticeably easier. On a 1.5-inch rise, that means a ramp at least 18 inches deep.
Can a robot vacuum climb a 1.5-inch threshold without a ramp?
Almost certainly not. Most robot vacuums are rated for about 0.6 to 0.8 inches (1.5 to 2 cm), and even newer lift-chassis models are rated around 1.2 inches (3 cm) on a single threshold. A gentle rubber ramp on each side is the reliable fix.
Do I need a ramp on both sides of the threshold?
Only if there’s a lip on both sides. Measure the rise from each floor. If the far side is flush, one ramp is enough; if it drops more than about 1/4 inch, add a second ramp sized to that side’s rise.
