Product Overview

Channel
Cooper B-Line’s metal framing channel is cold formed
on our modern rolling mills from 12 Ga. (2.6mm),
14 Ga.
(1.9mm), and 16 Ga. (1.5mm) low carbon steel
strips. A continuous slot with inturned lips provides
the ability to make attachments at any point.
Lengths & Tolerances

Custom lengths are available upon request.
Slots
Cooper B-Line’s slotted series of channels offer full
flexibility. A variety of pre-punched slot patterns
eliminate the need for precise field measuring for
hole locations. Slots offer wide adjustments in the
alignment and bolt sizing.
Holes
A variety of pre-punched
9
/16(14.3 mm) diameter hole
patterns are available in Cooper B-Line channels.
These hole patterns provide an economical
alternative to costly field drilling required for many
applications.
Knockouts
When used with series B217-20 Closure Strips,
Cooper B-Line’s knockout channels can be used to
provide an economical U.L. listed surface raceway.
Channels are furnished with
7
/8(22.2 mm) knockouts
on 6” (152 mm) centers, allowing for perfect fixture
alignment on spans up to 20’ (6.09 m).
Materials & Finishes (Unless otherwise noted)
Steel: Plain & Pre-galvanized
12 Ga. (2.6), 14 Ga. (1.9) and 16 Ga. (1.5)
Note:
A
minimum order may apply on special material and finishes.
Design Load (Steel & Stainless Steel)
The design loads given for strut beam loads are based on a simple beam condition using an allowable stress of
25,000 psi. This allowable stress results in a safety factor of 1.68. This is based upon virgin steel minimum yield
strength of 33,000 psi cold worked during rolling to an average yield stress of 42,000 psi.
For aluminum channel loading multiple steel loading by a factor of 0.38.
Welding
Weld spacing is maintained between 2
1
/2 inches (63.5 mm) and 4 inches (101.6 mm) on center. Through high
quality control testing of welded channels and continuous monitoring of welding equipment, Cooper B-Line
provides the most consistent combination channels available today.
