I used the bed rail fastners to connect wall sections in a portable trade show display. Worked great. They had a good tight fit when assembled, sturdy and hidden out of sight.
These brackets offer an invisible fixing method for bed construction. The worry of screwing into the end grain can be eliminated by blind doweling from the inside face of the bedrail. This method ensures a strong material for the screws to secure into. TIP: when assembling the bed apply wax to the mating faces to prevent any rubbing in use.
