Notes:
For factory assembled blocks on channel, prefix Catalog # with “0” and suffix
with number of blocks desired. Without channel (maximum of 6 sections)
delete “0”. See page 275 for dimensions and other details.
Example: Ten tubular screw sections preassembled on channel = 082410
For unpainted factory assembled blocks supplied with a removable marking
strip add -1 to Catalog Number.
For blocks with two or more different contact sections, imprinted marking
strips or special features; consult Technical Support.
Same part used for both panel and
channel mounting.
