Corner blocks are reversible so when you ask for a corner you will get the correct one every time.
Foam thickness is 2.625" on all forms.
Tie allows rebar lap splices to lay on top of each other for good flowability during concrete placement.
Ties touch vertically when stacked, eliminating form settlement.

Description

Insulated Concrete Forms (ICF) corner blocks make up ~15-20% of the ICF material needed in most commercial and residential projects.

Each 90-degree corner block has a patent-pending corner bracket design for maximum strength and stability. The 7/32" thick x 1-1/2" wide corner bracket connecting the inside and outside walls is unique to Fox Blocks, engineered to eliminate unintentional blow-outs during the concrete pour.

The Styrofoam Expanded Polystyrene (EPS) foam walls connect together with seven robust and full-length injection molded plastic ties.
