Soft-type polyethylene foam backer rod for controlling sealant depth in glazing and building joints. Bi-cellular and highly compressible, it seats into irregular and variable-width joints without gassing or bubbling the sealant. Sealants will not adhere to it, so no separate bond breaker is required.
It holds your sealant at the correct depth so the bead forms the proper hourglass profile and moves the way it was designed to, and it cuts the volume of sealant the joint consumes. Produced without CFCs or HCFCs.
Which diameter for your joint
The joint is the gap between the two pieces you are sealing — pane to frame, panel to panel, slab to slab. Measure that gap and pick the rod one size larger, so it squeezes in and stays put: roughly 25% larger than the gap, installed at 25% to 50% compression. A rod that drops in loose does nothing.

Delivery
Delivery is free across New York City and within 30 miles of our Jersey City warehouse, on any order — no minimum, delivered by us. From 30 to 50 miles it is free on orders of $2,000 or more; a smaller order at that distance, and every order past 50 miles, ships by FedEx or UPS at the rate the checkout shows for your address.
Big order going a long way? Talk to us before you check out. Parcel carriers charge heavy boxes by the pound, so several cases past 50 miles can cost more to ship by FedEx or UPS than it should. We book LTL freight on a pallet at our rates, which usually comes out far cheaper. Contact the office or press Get Volume Pricing above with the quantity and your ZIP code, and we will quote the freight the same or the next business day.
A single parcel cannot weigh more than 150 pounds. Where a volume price states that local delivery is included, that price covers the delivery.
Trade terms
Volume pricing is shown on the page wherever it applies; for a bigger quantity, a standing order or a job lot, tell us what you need and we will quote it.
