Custom Cherry Pickers, Utility Trucks & Bucket Trucks

Truck door seals on a bucket truckHeavy-duty trucks, including those with mounted cranes or specialized bodies with hydraulic frames, need protection from water damage, dirt, and debris. Truck cap seals, truck toolbox weather seals, door seals, and trims help ensure commercial work trucks can endure tough conditions on a variety of jobsites.

Trim-Lok’s work and bucket truck parts include:
  • • Edge trim for truck bodies, cabinets, toolboxes, and rough edges
  • • Trim seal weather stripping for hydraulic valve enclosures, doors, and windows
  • • Round rubber seal, or cord seal, where a push-in seal is needed

Bucket Truck Toolbox & Window Seals

Seals for trucks, boats, furniture, RVs and service trucks

Bucket trucks and utility trucks require heavy-duty rubber seals to protect the vehicle and its contents from the elements. Because they provide a water-tight seal, rubber truck seals are ideal when used as truck toolbox weather seals or to provide a protective window seal.

Rubber seals for trucks provide high-quality protection for vehicles that work in rainy or snowy areas and on construction sites with dirt and debris. As the No. 1 source for sealing rubber extrusions, Rubber-Lok provides custom, easy-install clip seals that fit and protect your bucket truck, dump truck, or electric utility vehicle. 

Edge Trims & Truck Door Seals

Trim-Lok’s flexible trim for trucks can be used across a wide range of protective and decorative applications for rough edges, such as on utility truck hoods and for truck door seals. Many OEMs and owners of private work trucks use our flexible PVC edge trim to prevent chips, nicks, and rust. 

Find the edge trim you need with our custom edge trim builder.

Weatherproof Truck Trim Seals

Trim for commercial work trucks, boat hatches, doors and RVs

Trim seals stay in place during extreme temperatures and weather conditions, protecting the contents behind the trim. All Trim-Lok trim seals come with an optional butyl or hot-melt adhesive sealant for a stronger grip and to prevent seepage. They are best used where there is an edge to which you can attach the trim, such as a truck cap seal.
