ChemLink, F1350GR E-Curb 6 In. MiniCurb Kit

The ChemLink E-Curb 6 In. MiniCurb Kit is a factory-assembled penetration seal solution designed for sealing round roof penetrations such as conduit, drains, mounts, and other supports. Prefabricated E-Curb components are slip-fit around existing penetrations and paired with sealant products to form a watertight perimeter without field-built pitch pans.

This kit combines precast nylon resin curb pieces with the necessary sealer and adhesive/sealant to support a full installation around the penetration. The 6-inch diameter configuration is suited to common small to medium penetration sizes where a compact, standardized roof seal is required.

Key Features

• Precast E-Curb components for sealing round roof penetrations
• 6-inch internal diameter MiniCurb configuration
• Slip-fit design for installation around existing penetrations
• Includes pourable sealer and structural adhesive/sealant in the kit
• Designed for use with multiple roof membrane types with appropriate priming

MiniCurbs are installed in the same manner as larger ChemCurbs,

1) Remove all asphalt or cement from the penetration with a wire brush and clean residual dirt and oil with

alcohol. Clean surrounding roofing material as well. (TPO should be primed with ChemLink TPO Primer)

2) Seal the base of the penetration with M-1 to prevent drainage of sealant into building.

3) Prime the penetration with a film of M-1 to 2 inches above the roof surface.

4) Coat the bottom of the flange with a double bead of M-1.

5) Place the coated MiniCurb components around the penetration and slip the edges together unitizing them

into a solid ring.

6) Coat Exterior Seam with Bead of M-1.

7) Firmly press the assembled MiniCurb down on the roof membrane until excess adhesive squeezes out at

the edges. Wipe off excess adhesive.

8) Fill the interior of the MiniCurb with 1-Part pourable sealer. Make sure the interior is filled to the top to

prevent water from accumulating at the top.

Q: Is this something people usually buy as a standalone item or as part of a larger order?

A: It’s commonly ordered on its own when sealing individual penetrations, especially when a full curb system isn’t needed.

Q: If I’m unsure whether the 6-inch size is right, what do people usually check first?

A: Most crews confirm the outside diameter of the penetration and allow room for sealant before choosing the MiniCurb size.

Q: When do crews typically decide to use a MiniCurb instead of building something in the field?

A: This usually comes up when consistency, speed, or repeatability matters more than fabricating a custom detail on the roof.
