Epoxy/Resin Mold Accessories
Peter Fillmore (Etobicoke, CA)
Excellent Product! HDPE Dividers

I purchased (2) 36" long 3/4" thick HDPE Dividers, as replacements for the thinner 1/2" dividers for my Epoxy Resin Mold from a different supplier (MRM). I cut these to 24" and used the excess to make clamping blocks. These thick dividers are very sturdy; and an upgrade from the thinner 1/2" originals which had started to warp. I had previously been using 2x4s covered in tuck tape to replace the warped dividers. This allowed me to maximize the space in my resin mold and get a full 6 boards in my pours, versus the 4 with the 2x4s covered with tuck tape.

They worked perfectly. The screws I got from another supplier were weak, and a couple of them snapped off. These were great quality.
