B-LINE SB2531 – Frequently Asked Questions

1) What is in the B-Line SB2531 isolation kit, and what does it actually do?
The SB2531 is an auxiliary support isolation kit for 1 inch x 2 inch support channel. It ships as a polyester fiberglass pad plus steel J-bolts, sleeve kits and 5/16"-18 hardware. The fiberglass pad and the sleeves separate the supported item from the steel channel so you get a dielectric break at the clamp point instead of metal on metal.
2) What thread size are the J-bolts on the B-Line SB2531 kit?
The hardware is 5/16"-18. If you are ordering spare nuts or washers to go with it, or matching existing clamp hardware on the run, that is the thread to buy.
3) Is the hardware in the SB2531 kit corrosion protected for a damp mechanical room?
The steel J-bolts and hardware come yellow zinc chromate plated, which is a standard indoor and sheltered-location plating. The pad is polyester fiberglass, so it will not corrode. For direct outdoor exposure or a washdown area, a stainless or hot dip galvanized clamp assembly is the usual call instead.
4) Why would I use a fiberglass isolation pad instead of clamping conduit or pipe straight to the strut?
Direct steel-to-steel contact between a copper or dissimilar-metal line and a steel channel invites galvanic corrosion, and it transmits vibration and noise straight into the structure. The fiberglass pad and sleeves in this kit keep the two metals apart at the support point. If you do not have dissimilar metals and no vibration concern, a plain pipe clamp on the channel is enough.
5) How do I identify the SB2531 on a submittal or reorder?
Order it as B-Line (Eaton) part number SB2531. The identifying description is the 1 inch x 2 inch support channel isolation kit, red pad, yellow zinc J-bolts and hardware.
