Colinktool Adjustable Roof Ladder Rack for Enclosed Trailers — 48–84" Length, 300 lb Capacity, Oxide-Finished Steel

Colinktool Adjustable Roof Ladder Racks are heavy-duty, telescoping trailer racks designed to mount on enclosed trailers and carry up to 300 pounds of ladders, lumber, kayaks, solar panels and other long cargo.

Built from fully welded steel with a protective oxide finish, this adjustable roof rack system fits a wide range of enclosed trailer widths and heights so you can haul bulky or long items without crowding interior space. The kit ships with mounting hardware, self-tapping screws and clear instructions for a do-it-yourself installation that secures cargo with included tie straps.

How does the Colinktool rack adapt to different trailer sizes?

The rack uses telescoping cross members and four adjustment points so it adjusts to most enclosed trailers between 4' and 7' wide. Length and height ranges let you set the system to suit short or long trailer roofs and maintain proper clearance.

• Fits trailer widths of 4', 5', 6' and 7'
• Length adjusts from 48" to 84" for varied load sizes
• Height range from 12.83" to 25" to match roof profiles
• Telescoping cross members simplify on-site fitting

What materials and corrosion protection are used?

The frame is fully welded from heavy-duty steel to deliver rigidity and a high-rated load capacity. An oxide coating adds corrosion resistance to protect the rack from weather and road wear without frequent repainting.

• Fully welded steel construction for structural strength
• Oxide coating resists rust and surface corrosion
• Durable finish reduces maintenance needs over time
• Hardware designed to withstand outdoor exposure

How easy is installation and what’s included in the kit?

The rack is designed for straightforward DIY mounting: pre-drill through the trailer wall, set the feet, then secure with the supplied self-tapping screws and bolts. The package includes clear instructions and the necessary mounting hardware so you have everything to get started.
