Polyurethane railing support block, required for rail lengths over 6′.


Our Polyurethane Railing Support Block comes in one size that fits all Poly Rail sizes.  Recommended for rail lengths over 4′.  Also use blocks under every section of curved porch railing, regardless of rail length.  The support block is 4″ high, and can be cut down if a shorter toe space is desired.  Cut a polyurethane railing support block just as you would work with wood materials.

The railing “kick-space” block, as they are sometimes called, can be easily installed with PL Premium polyurethane adhesive.
