B-LINE SB2129SD12TG – Frequently Asked Questions
1) What does the Eaton B-Line SB2129SD12TG side drop-out kit actually do on a cable runway?
It is a side drop-out, a curved steel piece that mounts to the side stringer of a cable runway so cables can leave the runway and turn down toward a rack or cabinet without bending over a sharp edge. The SB2129SD12TG is formed from 14 gauge ASTM A36 steel with a yellow zinc finish, so it supports the cable bend radius rather than just covering the opening.
2) What size opening does the B-Line SB2129SD12TG side drop-out cover?
The drop-out measures 10.25 inches wide by 4 inches high by 4 inches deep, so plan for roughly a 10-1/4 inch span along the runway stringer and about 4 inches of clearance below and outboard of the runway for the curve. Check that rack tops or ladder brackets are not sitting inside that 4 inch projection before you set the mounting point.
3) Is this a side drop-out or an end drop-out, and which one do I need?
This is the side version. Use a side drop-out where cable leaves the runway partway along its run, over the stringer, to feed a cabinet sitting beside the runway. If your cable has to exit off the cut end of the runway, that is an end drop-out instead and this part will not mount there. The SB2129SD12TG is the side configuration only.
4) Will the yellow zinc finish match the rest of my B-Line cable runway?
The finish here is yellow zinc over ASTM A36 steel, which is the plated hardware finish rather than a painted black or gray runway finish. If your stringers and ladder rack are painted black, this drop-out will not match visually, though it bolts up the same. For a color match, spec the drop-out in the same finish family as the runway you already have.
5) What is the part number to order the B-Line yellow zinc side drop-out?
Order Eaton B-Line model SB2129SD12TG. That single model number covers the 14 gauge steel side drop-out in yellow zinc; there are no finish or size options to specify with it.
6) How heavy is the B-Line side drop-out, and can one person install it overhead?
It weighs 2 pounds, so a single installer can hold it in place on an overhead runway while starting the hardware. The 10.25 inch width is the awkward part, not the weight.
