This page lists the back boxes Bell System sells for its door entry panels. Choose the model code from the drop-down. The 53 and 54 boxes are for Bell's SPA aluminium panels: the 53 codes are surface boxes and the 54 codes are flush boxes, each sized for a set number of buttons. The F and S codes are flush and surface boxes that Bell's price list names mostly by size letter or number.
Bell's SPA brochure says SPA panels come as standard with a low-profile surface mounting box moulded in black, or can be supplied with a flush fitting zintec back box and vandal resistant bolts. Its SPA dimension table gives the back box size for each panel from SPA1 to SPA10, and the model notes quote those sizes. Bell says these dimensions are approximate and may change without notice. Bell's sources do not give full sizes for the F and S boxes.
For an SPA panel, pick the box that matches the button count in its code, for example 53/3-4 for an SPA3 or SPA4 panel. Choose a 53 code for surface mounting or a 54 code for a flush recess in the wall. Bell's SPA brochure says panels above 10 buttons are flush fitting only, with sizes on application. For F and S boxes, check the size against the panel you have, as Bell's sources do not give their full sizes.

Match the button count. Bell's price list gives 53/1, 53/2, 53/3-4, 53/5-7 and 53/8-10 as surface boxes for SPA1 to SPA10, and the 54 codes as flush boxes for the same sizes. Bell's SPA table puts SPA3 and SPA4 in the same box size, and likewise SPA5 to SPA7 and SPA8 to SPA10.
Bell's SPA table gives a depth of 35mm for every flush back box from SPA1 to SPA10. The surface back box is 38mm deep for SPA1 and 43mm deep for SPA2 to SPA10. Widths are 73mm for the flush boxes and 100mm for the surface boxes, or 102mm for SPA1.
Bell's price list names most of them by size letter or number, without dimensions. The exceptions are the F-F, listed as 552 x 177, the S-6, listed for a 580 x 205 panel, and the F-E, listed for the DDA-EXT panel. Check the panel code and its measurements before ordering one of these boxes.
