Toilet Drop Closet Bolt Guide Cone Pair
A pair of 55 mm tall tapered guide cones that grip the 5/16 in closet bolts. When you lower the bowl, its bolt holes slide down the cones, so it lands centred on the wax ring and doesn't slide around and smear the seal. Each cone is 15.5 mm at the base and 12 mm at the tip, so it passes through standard toilet base slots and pulls straight up and off after the bowl is seated. The 8.4 mm bore has three crush ribs (7.4 mm across) that grip the threads, and the two cones print joined by a snap-off tab.
