Kawneer KW027088 – Frequently Asked Questions

1) Will Kawneer KW027088 pile weatherstripping fit a Trifab 451 transom bar?
Yes, if the transom bar is the OC type. The KW027088 pile weatherseal is made for the OC transom bar in Kawneer Trifab 400, 450 and 451 framing. It drops into the existing weatherseal race, so no frame modification or custom fabrication is needed. If your transom bar is a different Trifab profile, it is not the right seal.
2) How much weatherstripping comes on the KW027088 roll?
It ships as a 2500 ft bulk roll. That is contractor-stock quantity, meant for multi-opening replacement programs or a facility standardizing its Trifab transom seals rather than a single transom. You cut the lengths you need off the roll.
3) Is pile weatherstripping the right choice for sealing a transom bar, or should I use a bulb gasket?
Pile is what Kawneer specifies at the OC transom bar interface, and it is what KW027088 is. Pile seals against air infiltration, dust and light drafts by brushing against the mating surface, which suits a sliding or close-tolerance metal-to-metal joint at a transom. A compression bulb gasket is for a joint that closes hard against it, which is not how the OC transom bar interface is built. Match the original: pile in a pile race.
4) Is this a genuine Kawneer part or an aftermarket equivalent?
Genuine Kawneer service part, model KW027088, sold as a replacement part. That matters on Trifab work because the pile height and backing dimension have to match the original race to seal; a generic pile of the wrong backing will not retain properly.
5) We manage several buildings with Kawneer storefronts, all leaking air at the transoms. Does one roll cover a retrofit program?
A single 2500 ft roll is sized for exactly that kind of program, and it is the reason the part is sold in bulk rather than cut lengths. It restores weatherseal integrity in existing Trifab 400/450/451 installations, and because it uses the original race you are not touching the frames or the glazing to install it. Typical use is office, school, healthcare, retail, government and multi-tenant facade maintenance.
6) Can I use this weatherstripping on a residential storefront or patio door?
It is a commercial-rated part built for Kawneer Trifab curtainwall and storefront framing. On a residential door or window it has no matching race to seat in, so there is nothing to retain it. Use it only where a Trifab 400, 450 or 451 OC transom bar is in place.
