TERMINAL STRAP SUPPORT KIT
Designed to provide a simple and versatile method of mounting
terminal straps. The Z-shaped brackets are 1.50-in. (38-mm)
high with white finish. Brackets can be attached to panels or to
enclosure walls. A terminal strap is then installed on the brackets.
Terminal straps must be ordered separately. Two brackets are
furnished with each kit. Spacing between brackets will depend on
the number and size of terminal blocks installed on the terminal
strap. We recommend a maximum spacing of 15 in. (381 mm) for an
average installation.
