Pemko's extensive line of ADA compliant ramp thresholds answers the needs of architects, specifiers, building owners, installers and most importantly, physically challenged people. Flush, offset and variable application thresholds are versatile and suitable for installation in virtually any environment. This includes schools, hospitals, offices, restaurants, hotels, stadiums, storefronts and all public access buildings. Assemblies consist of interlocking components, eliminating the need to weld joints. Optional components such as miter returns can be sold as part of the assembly. Finish options include an aluminum mill finish and the PemKote™ skid resistant surface. Pemko also offers ramp systems in styrene butadiene (SBR) and recycled rubber.
Pemko's ramp threshold products have certain features and design elements that are beyond the standard of the industry. Our commitment to research and development, product testing, quality and service gives us the progressive edge in the applied science of door sealing. PemKote™ (AK) is highly recommended for all aluminum modular ramp threshold assemblies.
- Answers the needs of architects, specifiers, building owners, installers, and most importantly, physically challenged people. For use in schools, hospitals, offices, restaurants, hotels, stadiums, storefronts, and all public access buildings
- Assemblies consist of interlocking components, eliminating the need to weld joints. Features our interlocking ball-joint design which allows each component to flex and conform to uneven surfaces
- Available with cast aluminum miter returns
These are the "building blocks" which make up the assemblies. Components are generally sold as part of assemblies. Modular ramp threshold components meet or exceed ANSI/BHMA Standards and are Fire Rated, Classified and Listed to meet the requirements of UL10B.
Risers allow for greater offset conditions. When added to Pemko's Modular Ramp Systems, they allow offsets greater than 2-1/4" to be accommodated. Pemko's risers easily attach to the leg, adding 1/2" in height. Contact Pemko for more information.
Assemblies accommodate 1/2" to 2-1/4" floor offsets in meeting the 1:12 slope requirements of the "American with Disabilities Act". Even higher offsets can be accommodated by using Pemko risers, RAMP 13 and RAMP 14.
- Assemblies allow for custom fabrication (i.e. notching, side access extensions, etc.); please consult Pemko customer service
- Assemblies are provided NET length
- Assemblies are available for 7" Top Plate Offset, 3-1/2" Top Plate Offset and Variable applications
- Pemko highly recommends our specially designed miter returns. "MR" in a product number denotes that one-pair of miter returns (and one-pair miter return extenders, if applicable) are included. Otherwise, we recommend filling and feathering the threshold ends with grout. Do not leave threshold ends open
- Assemblies are supplied with #10 stainless steel wood screws. Stainless steel machine screws and expansion shields are available at an extra cost
Pemko recommends use of a "Variable" modular ramp threshold assembly to accommodate offsets from 1/2" to 1-1/4". These meet the 1:8 maximum slope allowance (ADA) for existing buildings. They may require a variance from some state building codes, even though they are ADA compliant. Ideal for use in cross traffic corridors where a minimal ramp projection may be required and a steeper slope may be allowed. Variable assemblies are supplied with #10 stainless steel wood screws. Stainless steel machine screws and expansion shields are available at an extra cost. Due to the variable angle of this ramp, miter returns are not available. Please fill and feather the threshold ends with grout. Do not leave threshold ends open. This variable ramp is sent un-drilled from Pemko. Due to the variance in the angle, it must be drilled in the field. For proper installation, it requires the RAMP7A to be placed under RAMP2A after the assembly is in place, then must be match drilled and anchored through both components. All assemblies meet or exceed the requirements of their underlying ANSI/BHMA Standards, are Fire Rated, Classified and Listed to meet the requirements of UL10B and are access compliant by having installed height differences not over 1/2" with allowable edge and slope conditions. All ramp products have ADA compliant 1:12 slopes.
Cast aluminum "wings" fit into each end of modular ramp threshold assembly, and are fastened to ramp mid sections with self-tapping machine screws. Miter returns for all modular ramp thresholds' neat, compact, and tight-fitting design replaces former mitering methods which reduces the need for costly and time-consuming grouting (filling and feathering the threshold ends), and eliminates previous custom miters which were welded and protruding.
Miter returns are supplied in pairs: One left-hand and one right-hand (example: WING10LH / WING10RH). Pemko can trim the length of each miter return to fit, but we strongly recommend trimming in the field. Miter returns are now available in three sizes: WING 10, WING 16 and WING EXTs are now included in order to completely fill ramp assembly ends for up to 2" offset or 2-1/4" flush conditions. WING EXTs work in conjunction with complete WING16s for these higher offset conditions. Miter returns are match drilled with each assembly. Contact Pemko for more information regarding sizes, lengths, materials and cut down suggestions.

- Part numbers are designated according to the following example: SBR1F – "SBR" refers to styrene butadiene rubber. "1" refers to the offset height to which the part flushes-out "F"
- Rubber ramps are sold in one foot increments up to 15-foot lengths
- Rubber ramps can be butted together for longer lengths
- Rubber ramps are cut square on each end but are available with molded rubber miter returns which can be glued to each end for a more pleasing appearance. To receive a pair of miter returns, add "MR" to the part number (example: SBR.5FMR)
- Rubber ramps have a superior grip, anti-slip surface and a "no bump" tapered lead edge. Rubber ramps are classified by Underwriters Laboratories, Inc.,® as a skid-resistant floor surface per UL standard for safety, UL410. Rubber ramps also meet the requirements of ASTM D 2047 and Federal Specification P-F-430C
- Fire Retardant Rubber ramps are easy to install on most surfaces (including wood, concrete, tile and asphalt), using a construction adhesive. Mechanical fasteners are not required and not recommended
- Rubber ramps are also portable. For temporary applications, an assembly which has been bonded together but has not been bonded to a base surface, stays in place by its sheer weight and can be removed from one opening and placed at another opening
- Rubber ramps are available for 1/2" and 1" offset heights
- Rubber ramps can be cross-cut to length or ripped to a custom offset height using a table or radial arm saw with a carbide-tipped blade. These modifications must be made in the field
