ME7494 Marcy Foam Setting / Spacer Blocks - 1/4" X 1/4" X 1" - 288 Blocks

        Even when using high-viscosity urethanes the glass may still sink too low into the urethane. One inch pre-cut blocks placed along the pinchweld will eliminate this problem. No guessing here, each block has a self adhesive backing so they stay secure during the installation process.                                                                                                     

Sold in a bundle of 4 pads - (288 blocks)
