Specialty Fiberglass Parts

Blackthorn can Manufacture ANYTHING out of Fiberglass!

Metal and Plastic parts are often not the most economical or practical option — THINK FIBERGLASS.

Pouring Lids

Fiberglass Pouring Lids are lightweight and surprisingly sturdy. They will not bend or bow.

Our Fiberglass Pouring Lids are domed to help concrete flow into the mold with ease, and feature a flat spot in the middle to hold extra concrete until the next part is ready to be poured.

Ideal for SCC Concrete.

Both ROUND & SQUARE shapes are available.

Available in “INNERS” and “OUTERS”

Fastening hardware available.
