ChemLink, F1351 E-Curb 9 In. MiniCurb Kit

The ChemLink E-Curb 9 In. MiniCurb Kit is a prefabricated roof penetration sealing solution designed to replace traditional pitch pans and simplify sealing around round penetrations such as conduit, drains, camera supports, mounts, and other structural penetrations. Each kit uses slip-fit components that assemble around the penetration and paired sealants to form a continuous watertight perimeter.

This 9-inch diameter MiniCurb kit comes with all required sealing materials included and is suitable for common roofing membranes. It’s sized for slightly larger penetrations where a compact, pre-engineered solution improves speed and consistency on the job.

Key Features

• Designed for sealing round roof penetrations including conduit and drains
• Slip-fit assembly around existing penetrations
• Kit includes both pourable sealant and structural adhesive/sealant
• 9-inch internal diameter configuration
• Prefabricated components reduce field fabrication time

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.

• Read and ensure that the most up-to-date MSDS and technical guidelines are being followed.

• Direct any questions to Technical Services at 800-826-1681 prior to starting the project.
• Chem Link offers a 10 year material warranty against leaks when applied in accordance with Chem
• Link application instructions stated above, using only specifically MiniCurb components.

Product type: Roof penetration sealing kit

Diameter: 9 inches (internal)

Intended use: Sealing around round roof penetrations such as piping and supports

Components included:
Two 9-inch MiniCurb curb rings
Two ½-gallon pouches of 1-Part pourable sealant
Two cartridges of M-1 adhesive/sealant

Q: Do most crews use this as a standalone item or alongside other sealing products?

A: Contractors often order it alone when addressing a singular penetration or in small groups for multiple penetrations.

Q: If I’m unsure whether the 9-inch size is right, what do experienced roofers check first?

A: They typically measure the penetration’s outside diameter and consider room for sealant to ensure the MiniCurb fits properly.

Q: When does using a prefab MiniCurb kit make more sense than building a custom solution?

A: Many crews choose a prefab kit when they want speed and repeatable sealing results instead of field-built patches or pitch pans.
