You should never use a flange spreader to hold open flanges while work is being performed. Now you don’t have to, with the SMP Chock-O-Lot.

 

Used in tandem with SMP’s Pop-It tool, the SMP Chock-O-Lot is ideal for getting a better bite.

 

The SMP Chock-O-Lot is adjustable from 1/8” to 2” of width with 1/8” increments and features a tie-off ring to better hold flanges open.
