Product overview
Slide-on fork extensions let a standard forklift safely carry longer, wider and odd-shaped loads such as lumber, pipe, furniture, crates and oversized skids. They slip over your existing forks in seconds, lock in place with a steel retaining strap, and come off just as quickly when you need standard-length forks again.
Construction and features
- Easy slide-on design, with no tools needed to install or remove.
- Steel retaining strap stops the extensions from sliding off the forks during use.
- Fits forks up to 2 inches thick.
- Fork extension capacity: 4,000 lbs.
- Sized for 4-, 5- and 6-inch-wide forks, in lengths from 54 to 96 inches.
- Heavy-duty welded steel construction in a safety-yellow finish.
- Sold in pairs.
Choosing the right size
Match the extension to your forks before ordering:
- Fork width: measure the width of one fork, then choose the 4-, 5- or 6-inch series. The extension sleeve is 1 inch wider than the fork it fits.
- Fork thickness: forks must be no more than 2 inches thick.
- Fork length: an extension may not extend more than 50% beyond the existing fork. In practice, the extension should be no longer than 1.5 times your fork length. For example, 48-inch forks can take extensions up to 72 inches.
Models and specifications
All fork extensions are sold in pairs. The last column shows the shortest fork each length can be used on under the 50% rule.

Storage wall bracket
Keep fork extensions off the floor and out of the way when they aren’t in use with the fork extension wall bracket (JMBL282). It’s an all-welded 6 x 8-inch bracket that mounts to a wall or column. You need one bracket for each pair of fork extensions. Mounting hardware is not included.
Safety and ordering notes
Always confirm that the forklift’s rated capacity, with the extensions fitted and at the load centre you’ll be using, suits the load. The extension capacity does not raise the forklift’s own capacity. Check that the retaining strap is secured before lifting.
In the inquiry form, include the part numbers, the number of pairs, your fork width, thickness and length, and your delivery location. Add a wall bracket for each pair if you’d like storage.
