Edwards 757A-SBW — white indoor surface box for 757 Series re-entrant speakers and speaker-strobes.
The 757 Series appliances flush-mount into the Edwards 960A-4SF box. Where there is no cavity to sink a box into, Edwards supplies colour-matched surface boxes instead, and this is the white indoor one. Indoor is the manufacturer word, not a shop qualifier: Edwards prints Surface Box, White, Indoor here.
- Edwards ordering table entry reads Surface Box, White, Indoor
- Red is the standard housing colour across the series; suffix W denotes white
- The surface-mount detail is dimensioned 5 5/8" (143 mm) square by 3 9/16" (91 mm) deep
- Combination 1/2" and 3/4" conduit knockouts in the top, bottom and back
- Serves 757 Series 25 V and 70 V speakers and speaker-strobes, themselves 5 1/2" (140 mm) square by 5/8" (16 mm) deep
The same block holds 757A-SB (red indoor), 757A-WB and 757A-WBW (red and white weatherproof), 960A-4SF (flush) and 757A-BDF and 757A-BDFW (bi-directional frames). Edwards allows outdoor use of the 757 Series only in a weatherproof box, so do not specify this box outside.
