Product Details

Boaters love Ethafoam. This closed-cell polyethylene foam material provides resilient cushioning for dry box lids, padding under decking and equipment protection.
  • Available in white or black, these 1" and 2" thick blocks have a density of 2.2 pounds per cubic foot.
  • The foam can be easily shaped with a razor blade, electric carving knife or hot-wire cutter.
  • H2 Glue, # 50203.01, is an excellent adhesive for bonding the foam to dry box lids and other items. You can also bond layers of the foam with this adhesive.
We fold the foam for shipping. Please specify in the Shipping Comments section during checkout if you would like the foam shipped flat.
