Pass & Seymour BOX40 – Frequently Asked Questions

1) Is the Pass & Seymour BOX40 grip UL listed for industrial panel work?
It carries both UL and CSA listings, which is what an inspector or a spec on a commercial or industrial job typically calls for on a cord grip. The CSA listing also covers you on work crossing into Canada.
2) What is the Pass & Seymour BOX40 strain relief grip used for?
The BOX40 is a wide range strain relief grip that clamps and supports cable where it enters an enclosure. It gets used on junction boxes, power distribution centers, industrial control panels and machine tool wiring, holding the cable so vibration and pulling load land on the grip instead of the terminations. An insulated bushing comes with it to keep the jacket off the sharp edge of the knockout.
3) Does the BOX40 come with the insulated bushing or do I order that separately?
The bushing ships with the grip. Nothing else to order for the edge protection side of the install.
4) Will the BOX40 fit in a tight enclosure?
The grip body measures 0.5 x 0.54 inches, so it takes up very little room inside a crowded junction box or control panel. Allow clearance beyond that for the cable bend past the bushing.
5) Can one BOX40 grip handle more than one cable diameter?
It is a wide range grip, meaning a single part covers a span of cable sizes rather than one fixed diameter. For MRO stocking that means fewer part numbers on the shelf to cover the cable you actually run.
