Pemko - S88D18 SiliconSeal Adhesive-Backed Fire/Smoke Gasketing, Dark Brown Silicone, 0.5" W x 0.25" H x 18' L

It worked perfect for sealing my Winchester fire safe. I added it to the existing seal to add a better seal and help remove the amount of movement the door had when closed. Now it is seal perfectly with no movement.

Stops drafts

Installed this on the door jamb of my vault to protect against a potential fire. Easy to install. Cut with scissors.

Material is flimsy and thin walled.

worked very will in my application.

I put a wireless hygrometer to measure the humidity in my safe and was shocked at how much humidity there was! I used dessicants and such but after a day or so they’d be saturated. I live in south florida and it is very humid. My Harbor Freight safe did not seal out any of it, air could pass freely through the gaps around the door. A Stack on model I have had the same problem. This was exactly what I was looking for. It sealed the door way perfectly. I also used the pemka slim seal where the door touches against the side on the hinge side. Now I have to give a tug on the door to open it and I get a nice woosh as the seal is released. Amazed how well this worked!

Great value, worked well for top & sides but not intended as a bottom sweep, wore out quickly, I'll have to find something else for bottom.

The product finally stopped the drafts of my entry door.
