A: yes, 3.75 x 100 = 375 ft
A: Hi Teresa, The Grip-Rite 3.75 Ft. long, 1 1/2 inch wide shim is intended to be used behind drywall, between the drywall and bowed or crooked stud. When I used the shims I used a staple gun with 3/8 inch long staples to hold the shim(s) in place before placing the piece of drywall against the studs for installation. The shims can easily be bent and torn to length by hand. The shims can be used behind water proof drywall against the bowed or crooked stud (see picture below) for a shower wall. Finish the drywall for the shower wall in the normal way and the shim should should never see the moisture. I hope this helps. Chipmaker
A: This can be used for any application where you have studs that aren’t properly aligned.
A: I would be reluctant to use paper shims behind a shower wall. If one used one of the new roll on water proofing materials like Hydroban between the tile and the backer board the shims would probably be ok, but a more moisture and humidity resistant material would be cheap insurance.
A: Absolutely! These shims are perfect for that application. I personally use them for a multitude of different tasks, but mostly to align new finishes to match up to existing finishes
