Questions about this item

Which existing hardware does the 70-1091-1 bracket attach to?

It is compatible with Grainger part numbers 48WH75, 53KJ78 and 53KJ79, and manufacturer model numbers 70-1094, 70-1095 and 70-1096.

Will the aluminum bracket cause galvanic corrosion against my steel dock frame?

The bracket is made of aluminum with a black finish; direct contact between dissimilar metals in a marine environment can promote corrosion, so use isolating washers or coatings if mounting to steel.

How do I confirm the bracket is holding securely after installation?

Tighten the two included heavy-duty tie straps until the bracket cannot shift laterally or vertically, then inspect that the 3-inch length, 5 3/4-inch width and 6-inch height sit flush against the mounting surface.
