Product Description
CRL Closed Cell Backer Rod is a round, flexible, closed cell polyethylene foam with an exterior "skin" used as a backing and thickness control device for elastomeric and other cold-applied sealants. The backer rod becomes an integral part of the joint into which it is installed and therefore is available in a range of diameters to accommodate joints from 3/16 inch to 1-5/8 inch. It limits the depth of the sealant, therefore preventing excessive use of sealants. Because the sealant will not bond to the "skin" of the rod, it can stretch and recover with joint movement, with minimal stress being put on the points of adhesion to the substrate

Good Backer Rod
By Matt
This is great for concrete and other applications. My only complaint is that it's advertised as 100 ft Roll and did not come in a roll. Rather, it comes all bunched up in a box. A roll, as pictured, would make both application and storage of leftovers easier.

Product worked perfectly
By Slowalkintexan
Product was exactly what I needed for what I needed it for. A on typical use, however, it worked great.

Punch a hole in the box...
By Joel Denney
...large enough to be able to pull knots and tangles through (1" or so), since - as everyone notes - it doesn't come on a spool as pictured. But just take it out of the box and find the right end to push through the hole you made. (I.e. if it *were* on a spool, the end you'd use first. Is that the Beginning or the End? And who cares?). Then, obviously, carefully cram it back in the box so it's coming off the top of the pile.
I've only had a couple tangles/knots. No big deal. (The box might even be better than a spool, since it's not going to run off).
What I don't yet know (and why I only "Like" it, not "Love" it) is how resistant it's going to be against grass and weeds growing through it, now that I've found a caulk that resists that junk (I hope, though only time will tell - which is why I'm not naming the caulk... yet)
