B-LINE SB2529A – Frequently Asked Questions
1) What is in the B-Line SB2529A top angle isolation kit?
The B-Line (Eaton) SB2529A is an auxiliary support isolation kit built around a 2 in x 2 in top angle. It includes a polyester fiberglass isolation pad plus a plate, J-bolts and hardware in steel with a yellow zinc chromate finish. The fiberglass pad is what breaks metal-to-metal contact between the support angle and the strut or channel it clamps to.
2) What bolt size do the J-bolts in the SB2529A isolation kit use?
Hardware size is 5/16 in - 18, so the J-bolts and nuts take a 5/16-18 thread. If you are matching an existing support run or ordering spare nuts and washers, that is the thread to buy.
3) Why use a fiberglass isolation pad on a pipe or conduit support instead of bolting steel to steel?
An isolation pad separates dissimilar metals and interrupts the direct metal-to-metal path at the support point, which is how galvanic corrosion and transmitted vibration or noise start on a rooftop or mechanical-room support run. The SB2529A uses a polyester fiberglass pad for that separation while the steel plate and J-bolts carry the clamping load.
4) Is the steel hardware in the B-Line SB2529A kit coated for corrosion resistance?
The plate, J-bolts and hardware are steel with a yellow zinc chromate finish. That is a plated indoor and sheltered-exterior finish, not hot-dip galvanized, so for continuously wet or coastal exposure specify a galvanized or stainless support kit instead.
5) What part number do I order for the B-Line Eaton top angle isolation kit?
Order MPN SB2529A from B-Line (Eaton). It is the top angle isolation kit configuration, 2 in x 2 in angle with 5/16-18 hardware.
6) How much does the SB2529A support kit weigh per kit?
Each SB2529A kit weighs .51 lb, so added dead load on the structure is negligible even across a long run of supports. Order by kit, one per support point.
