Aluminum Stake Pocket Insert — Fits Manac, Trailmobile, and Dorsey Trailers
Stake pockets are not standardized. A stake that drops straight into one trailer sits loose in the next, and a loose stake is a stake that rattles out.
This insert takes up that difference. It is 8" x 3-9/16" x 1-9/16", weighs 1.5 lbs, and is made from high-strength, lightweight aluminum. It fits Manac, Trailmobile, and Dorsey step deck trailer systems only, taking stakes 2.875" x 1-5/16".

Why an Insert Exists
Trailer manufacturers cut stake pockets to their own dimensions. A stake sized for one make will sit loose, or not sit at all, in another.
The insert bridges that. It fits Manac, Trailmobile, and Dorsey step deck trailer systems only and accepts 2.875" x 1-5/16", which means a standard stake seats tight rather than rattling.
A stake that moves in its pocket wears the pocket. Over a few seasons that turns a fitting problem into a trailer repair.
Weight and Material
At 1.5 lbs each, a full set of these is not a payload consideration. That is the point of aluminum here.
Steel inserts corrode inside the pocket where nothing can be seen or serviced, and they end up seized. Aluminum does not.
The insert measures 8" x 3-9/16" x 1-9/16". Check that against your pocket before ordering a full set.
