Bullnosed front edge, does not have side returns. For stairs with side returns, consider using our Flush Stair-nose and cutting a miter for the return.

If you have stairs that have side returns, use SuperCore Stair nosing to complete your step.  Stair nosing is made in 90" lengths.  You need to miter cut the return to finish the sides of the step. 

Most installers seem to use Loctite PL Premium for this application and sanding and "roughing up" your contact points would improve the bond.
