How it connects
The tubular steel strut passes through the keyed collar aperture; keyed notches along the strut align and lock within the aperture tab to transfer compression directly into the structural rim joist.
Male and female halves
Female stamped keyed aperture on the ledger connector plate mating with a male notched steel compression tube.

Common sizes
- BVLZ descriptions give both 1-1/8–1-3/8 in compression-strut OD and a 31/32 in (24.6 mm) aperture in a 12-gauge ledger plate. Confirm the exact kit drawing rather than treating these as the same dimension.

How to recognise it
