A metal core adds strength and stability, making this trim more durable than standard rubber trim. Made of rubber, it resists abrasion better than plastic trim. Use it to protect the edges of panels, boards, signs, and mirrors from impact.

Rubber Trim Selector Packs

Sample multiple sizes and styles of rubber trim.

High-Temperature Rubber Trim

This trim withstands temperatures up to 450° F, which is generally twice as high as our standard rubber trim. Use it to protect the edges of panels, boards, and signs from impact. Made of rubber, it resists abrasion better than plastic trim.

Heavy Duty High-Temperature Rubber Trim

A metal core adds strength and stability, making this trim more durable than other high-temperature rubber trim. It withstands temperatures up to 400° F, which is generally twice as high as our standard rubber trim. Use it to protect the edges of panels, boards, and signs from impact. Made of rubber, it resists abrasion better than plastic trim.

Food Industry Rubber Trim

Guard the edges of panels, signs, glass, and other surfaces in food plants from frequent bumps and scrapes. This trim is FDA compliant, so it’s safe to directly touch food.

Conductive Rubber Trim

With a surface resistivity of 1.4 ohms, this trim safeguards equipment from static electricity by diverting electrostatic charges quickly. Made of rubber, it resists abrasion better than plastic trim. Use it to protect the edges of electronics equipment and circuit boards from impact.

Plastic Trim

Select this plastic trim for its chemical resistance. Often used on panels, boards, signs, and mirrors, it protects edges from impact.

Heavy Duty Plastic Trim

This trim has a metal core for added strength and stability. Made of plastic, it's also chemical resistant. Use it to protect the edges of panels, boards, signs, and mirrors from impact.

Slippery High-Temperature Plastic Trim

This trim withstands temperatures up to 500° F, which is generally twice as high as our other slippery trim. With a slippery surface, it minimizes friction between parts and is often used on conveyor rails, chutes, and guides. Made of plastic, it's also chemical resistant.

Sample multiple sizes and styles of heavy duty plastic trim.

Food Industry Plastic Trim

This trim is suitable for use in food preparation and processing environments. It's also chemical resistant. Use it to protect the edges of panels, boards, signs, and mirrors from impact in food processing applications.

Flame-Retardant Plastic Trim

This trim meets FMVSS-302 for Federal Motor Vehicle Safety Standards for flammability, UL 94 HB flame requirements, and NFPA (National Fire Protection Agency) standards. Made of plastic, it's also chemical resistant. Use it to protect the edges of panels, boards, and signs from impact.

Conductive Plastic Trim

With a surface resistivity of 10 ⁵ ohms this trim safeguards equipment from static electricity by diverting electrostatic charges quickly. Made of plastic, it's also chemical resistant. Use it to protect the edges of of electronics equipment and circuit boards from impact.

Metal Trim

Made of aluminum or stainless steel, this trim withstands heavy impact for maximum surface protection. It's often used on panels, boards, signs, and mirrors to protect the edges.

Flexible Metal Trim

This nylon-coated stainless steel trim combines strength with flexibility to hold snugly on flat, round, and irregular-shaped edges. It can also protect wire, cable, and hose.

Cushioned Flexible Metal Trim

Cushioning on the top provides added protection from impact. This nylon-coated stainless steel trim combines strength with flexibility for a snug hold. It can also protect wire, cable, and hose.

High-Temperature Flexible Metal Trim

Designed to withstand temperatures up to 800° F, this stainless steel trim is good for use with ovens, boilers, and heat shields. It combines strength with flexibility to hold snugly on flat, round, and irregular-shaped edges.

Foam Trim

High-Temperature Foam Trim

This trim withstands temperatures up to 450° F—more than twice as high as other foam trim. Designed to cushion during impact, it protects equipment and surfaces from damage.

High-Visibility Foam Trim

Black and yellow stripes create a visual alert to draw attention to equipment and obstructions. Designed to cushion during impact, this foam trim protects edges on posts, shelving, and other surfaces from damage.

Glow-in-the-Dark Foam Trim

Even in the dark, this black and yellow striped trim draws attention to equipment and obstructions. Designed to cushion during impact, it protects edges on posts, shelving, and other surfaces from damage.

Raw Materials

Super-Cushioning Foam U-Channels

The open top allows these foam U-channels to slide over and cushion an edge.

Ultra-Strength Lightweight Carbon Fiber U-Channels

Often used to make railings, edge covers, and other structural framing parts, these carbon fiber U-channels add stiffness and strength to applications without adding a lot of weight.

Arc-Resistant GPO3 Fiberglass U-Channels

Offering excellent arc and track resistance, this GPO3 fiberglass is often used for electrical applications in humid environments.

Arc-Resistant GPO3 Fiberglass Hat Channels

Unlike similar U-channels, these GPO3 fiberglass hat channels have flanges for mounting to flat surfaces. Use them to route and insulate wire in humid environments.

Ultra-High-Temperature Carbon Fiber U-Channels

Unlike metal channels, these carbon fiber U-channels won’t warp at extreme temperatures, so they’re ideal for heat treating and furnace fixtures.

Structural FRP Fiberglass U-Channels

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.
