B-LINE SB2135BZ – Frequently Asked Questions
1) What is the B-Line SB2135BZ runway splice used for?
The SB2135BZ is a pair of splice clamps used to join runway stringers end to end, so two lengths of cable runway become one continuous run. You get two clamps in the pack, which is what it takes to splice one joint (one clamp per side of the stringer).
2) Is the SB2135BZ splice for cable runway or for strut channel?
It is a runway splice, made to connect runway stringers. It is not a strut channel coupling or a cable tray splice plate. If you are joining lengths of channel or ladder tray, you need the fitting made for that system instead.
3) How many SB2135BZ splice kits do I need for a full runway installation?
Order one SB2135BZ pack per splice joint. Each pack is a pair of clamps covering a single stringer connection, so a run made of four 10-foot stringer sections joined on both sides of the runway needs a kit at each joint on each stringer. Count your joints, not your sections.
4) What material and finish are the B-Line runway splice clamps?
Black zinc plated ASTM A570 structural steel. The A570 hot-rolled carbon steel is what carries the load at the joint, and the black zinc plating gives corrosion resistance plus a dark finish that blends with black runway in a data or telecom room.
5) What size are the B-Line SB2135BZ splice clamps?
Each clamp measures 4 x 1.5 x .62 inches, and the pair weighs 1 lb. That compact footprint means the splice sits tight against the stringer without eating into the cable channel above it.
6) Does the black zinc finish on the B-Line splice match black runway already installed?
The clamps come in a black zinc finish, which is the standard match for black-finished B-Line cable runway. For a facility standardizing on one look across a comms room, specifying the BZ suffix keeps splices consistent with the stringers they join.
