NOR 720

Seal Nor 720

What size rout does the seal fit into?

The NOR 720 fits into a groove of 3mm wide by 4mm deep.

Can I use the NOR 720 on latched doorsets?

As this seal is so small and fits into a 3mm groove it can be positioned either side of most common ironmongery.

Do I fit the NOR 720 seal to the frame or the door leaf?

Since this seal is symmetrical it can be fitted to either the frame or the door leaf in either single or double rows.

Would I require a separate smoke seal if I use the NOR 720?

No. Since the NOR 720 is a continuous acoustic seal it acts as a smoke seal, better in some ways than standard intumescent smoke seals.
