Pemko 3151CN 36 – Frequently Asked Questions

1) How big a gap under the door will the Pemko 3151 sweep close?
The 3151 surface sweep seals a gap of up to 1 inch between the bottom of the door and the threshold or floor. Pemko's recommendation is 1/16 inch of compression on the neoprene, so set the sweep so the insert just bears on the floor rather than dragging hard. If your undercut is larger than an inch, a surface sweep of this height won't reach it and you want a door bottom or an adjustable threshold instead.
2) Does installing a Pemko 3151 sweep require any machining of the door?
No prep is needed. The 3151 is a surface-applied sweep: the aluminum plate screws to the face of the door at the bottom, so there is no routing, no kerf and no mortise. That's what makes it the usual choice for retrofit work on doors already hung. The plate itself is 1-1/4 inches high by 1/2 inch wide, so it stands proud of the door face by half an inch, worth checking against any astragal or stop it will pass.
3) How do you adjust a Pemko 3151 sweep if the floor is uneven?
The mounting holes in the 3151 are slotted, so after the screws are started you can slide the plate up or down before tightening. On a floor that rises across the swing, set the height off the high point and let the neoprene take up the rest. Aim for about 1/16 inch of compression at the tightest spot, otherwise the door will drag and the closer will fight it.
4) Is a neoprene sweep insert the right choice for an exterior door, or should I use vinyl or brush?
Neoprene is the one to pick where the seal takes chemical or weather punishment. The 3151's synthetic rubber extrusion resists abrasion, hydraulic fluids, alkalis, heat, ozone and weather, which is why it turns up on shop doors, mechanical rooms, loading areas and exterior openings. It also holds a tighter seal against wind, rain and snow, and against light, smoke and fumes, than a brush insert does. Brush is better where the floor is rough or a carpet transition would tear a solid gasket.
5) What finish does the Pemko 3151 sweep come in?
Clear anodized aluminum, on both the 36 inch and 48 inch pieces. That's the mill-look silver finish that reads neutral against aluminum storefront and hollow metal alike, so it's the safe pick when you're standardizing sweeps across a building and the doors aren't all the same color.
6) Can the Pemko 3151 be used on interior doors to cut noise and light between rooms?
It works there. The 3151 reduces infiltration of light and air along with smoke and fumes, so it's commonly run on corridor, classroom and office doors where the undercut is letting light and hallway noise through. The aluminum plate is the same 1-1/4 by 1/2 inch section indoors or out, and interior floors are usually flatter, which makes the 1/16 inch compression setting easier to hold across the full width.
