Some entrances need more ramp than a portable can give at a safe slope, yet nothing like a configured system with landings and turns: a stoop, a porch edge or a side door with a straight approach and a rise between 3 in and 20 in across the range. The PVI OnTrac is built for that middle ground. It is a freestanding aluminum ramp with handrails on both sides, sold as a single straight run in eight lengths from 3 ft to 10 ft, 36 in wide between the curbs, that stands on its own legs and bolts together with hand tools.
It is a straight run only. PVI lists the OnTrac only as straight ramps from 3 ft to 10 ft, with no platform, turn or resting landing, so a doorway that needs a level landing or a path that has to bend calls for the PVI Modular XP instead. PVI's assembly manual sets the slope between 1:12 and 2:12 and notes that the ADA recommends 1:12 where space allows; PVI's catalog adds that an occupied chair or scooter should never go steeper than 2:12, and then only with an assistant, with 3:12 reserved for unoccupied loading. Freestanding does not mean loose: the manual requires the ramp to be anchored at both its upper and lower ends.
Key Features
Handrails on both sides, standard: Every ramp section carries a left and a right handrail assembly and the entrance gets its own pair, per PVI's assembly manual; an ADA extended handrail is available on request.
One run per length: PVI welds 2 ft, 3 ft and 4 ft sections and splices them to make each of the eight lengths, so you order the length and receive the whole ramp.
850 lb across two axles: PVI's rating is 850 lb with both axles of a chair on the ramp and 425 lb when a single axle is loaded.
36 in usable, 42 in overall: The deck is 36 in between the 4 in curbs, and the handrail posts bring the overall width to 42 in, per the assembly manual.
Freestanding with anchored ends: The ramp needs no permanent attachment to the building; it rests on height-adjustable support brackets and is fixed to the ground at the hook bracket and support brackets with concrete screws.
Lateral-groove aluminum planking: The slip-resistant grooves run across the deck, and the all-aluminum build is weather resistant and needs little or no maintenance, per PVI.
Packs down for assembly on site: PVI welds the OnTrac in 2 ft, 3 ft and 4 ft sections that splice together, so even the 127 lb 10 ft ramp arrives as sections rather than one piece.
Who It Is For
A home with a porch or raised entry of 3 in to 20 in and a straight approach, where the ramp will stay put for a season or longer: a parent moving in, a hospice or rehab period, or a rental where nothing can be built onto the house. The handrails make it a fit for people who walk with a cane or walker as well as for wheelchair and scooter users, and it is graded for commercial or residential entryways. A rise above 20 in, a turn, or a level landing at the door needs the PVI Modular XP; a ramp that travels between addresses every week is a job for a PVI folding portable.
Dimensions
Lengths: 3 ft, 4 ft, 5 ft, 6 ft, 7 ft, 8 ft, 9 ft and 10 ft, all 36 in usable width and 42 in overall
Occupied-use rise range: 3 in to 6 in (3 ft), 4 in to 8 in (4 ft), 5 in to 10 in (5 ft), 6 in to 12 in (6 ft), 7 in to 14 in (7 ft), 8 in to 16 in (8 ft), 9 in to 18 in (9 ft), 10 in to 20 in (10 ft)
Curb height 4 in on both sides
Measure from the ground to the top of the step or landing the ramp will meet. At PVI's recommended 1:12 slope each 1 in of rise needs 1 ft of ramp, so a 7 in rise calls for the 7 ft ramp; the upper figures in the rise table reflect the 2:12 slope PVI allows for occupied use with an assistant present.
Installation
PVI says the OnTrac installs in minutes and does not publish a time. Its assembly manual lists the tools: a ratchet with 1/2 in deep well and 7/16 in sockets, a 1/2 in wrench, a 1/4 in masonry bit, a 5/32 in Allen wrench, a #2 Phillips bit and a tape measure. Carriage bolts, hex bolts, concrete screws, lock nuts and washers are supplied.
Fit the caps to the handrail posts and bolt a left and a right handrail assembly to each ramp section, plus two entrance handrail assemblies at the entrance base.
Join the ramp bases with the ramp splices, add the entrance base with its entrance splices, and fit the hook bracket at the top end.
Set the entrance handrail first, then the ramp handrails through the handrail splice, and finish with the lower tubes and end loops.
Bolt the support brackets to the entrance posts and set them to the height of the landing.
Move the ramp into its final position, check that the slope sits between 1:12 and 2:12, then anchor it through the hook bracket and support brackets with the concrete screws.
Leave all hardware loose until this last step, then tighten everything.

A 1:12 slope means 12 inches of ramp for every inch of rise. The bigger the second number, the gentler the climb. Gentler is always safer, so verify local building code before installing.
Why slope matters
Slope
Incline
Intended Use
1:12
≈4.8°
Independent wheelchair use. The ADA standard.
1:6
≈9.5°
Steepest acceptable for an occupied chair or scooter, and only with a qualified helper.
1:4
≈14°
Unoccupied transport only, with no one riding.
Read the ratio as rise to length: 1:4 means every inch of rise needs 4 inches of ramp, so it climbs three times faster than 1:12. Some manufacturers write these same two slopes as 2:12 and 3:12, which are identical inclines in unreduced form.
Use the longest ramp your space allows and follow your equipment’s owner manual. A rise over 30 inches needs a landing or platform.
