Sioux Chief 427-PB Plumb Perfect Open-End Closet Bolts, 2-1/2" & 3-1/2" Lengths

Sioux Chief's 427-PB Plumb Perfect closet bolts are open-end toilet flange bolts built for professional rough-in, remodel, and toilet-replacement work. Each bolt is 100% corrosion-proof and engineered to exceed 1,100 lbs. of tensile strength, with a base that loads into any closet flange and stays upright without spinning while the toilet is set. This box ships 50 pairs of bolts in both 2-1/2" and 3-1/2" lengths, so installers have the reach on hand for flanges set at different heights above the finished floor.
