KINDORF® METAL FRAMING SYSTEM METAL FRAMING CHANNEL & ACCESSORIES
Design data
Kindorf
®
self-aligning channel nuts are designed to
provide resistance to pull out and resistance to
side slip in excess of the full strength of the channels
with which they are used. The extreme resistance to
side slip results from the unique design of the
alternate teeth, spaced and designed to develop a
wedging action that increases with pressure or load.
Load ratings of steel channel and insert nuts
(B-910-1/2 or B-911-1/2) when used in slot of 12 ga.
