So how many squarebody slamming doors can you repair for under $3. Anyone want to guess??? I was told about this trick long ago. Finally got frustrated enough today, and I happen to be out and about and dropped in at Lowe's for a piece of plumbing. This is a 5 foot stick of 1/2 PEX sold in the plumbing dept pre cut. I got it for $1.98 plus tax to a total of $2.14.
