CONTROLLED AND GUIDED FLANGE SEPARATION TOOL
You’ll never again have to resort to “hammer and chisel” methods that waste time and effort. Flange spreaders should be used in pairs to provide even spreading force.
Use HFS3A for applications where total thickness of f langes and max. spread gap is 3 or less, and flange bolts are a min. of 0.69" diameter.
Use HFS6A if total thickness of flanges and max. spread gap is 6" or less, and flange bolts are a min. of 0.81" diameter.
