Decking and floor frames rely on the joists sitting square and steady on the bearer, and that is the job this bracket does. This Dunnings joist support is an Australian made galvanised connector that ties a joist down to the bearer below it.
The pre-formed shape cradles the joist and spreads the load, so the frame stays solid instead of working loose underfoot. Pre-punched holes take your nails or screws with no drilling guesswork. The galvanised Galvabond finish keeps the rust off, which matters under a deck where the weather gets in.
This one suits a 120mm by 35mm joist. Full dimensions are in the tabs below. Chasing a box or a bulk lot for a deck frame? Give the store a call and we will sort it.
