Nylon grommets for TJIs

jfox Member Posts: 44
I have some grommets for sleeving holes in TJI type joists with 3/8" webs. They are rated for 275* and fit any size hole.

The manufacturer's web site is

A bag of 25 pieces, one foot long, is $8.75. ($.35/foot). (They are not continuous coils even though the web site says they are).

I got 2-3 holes per piece, about 1/4 the price of insulator type sleeves. 4500 square foot house used about 50'.

Please email me if you are interested, or call.
