White Silicone Toilet Seat Bumpers 7 Rubber Replacement Safety Bumper Caps Tips With Hardware For Toilet Bowl Protection Non Slip Shock Absorbing Seat Renovators Supply Manufacturing. Visit the Renovators Supply Manufacturing StoreBe careful when installing these toilet seat bumpers.Replacing toilet seat bumpers can present problems. Drill pilot holes depending on the screw size, and be careful not to drill through the toilet seat. You may want to file or grind off the sharp ends of the screws so that they do not get pushed through the seat and cause stab wounds. If you have nylon screws available, use them instead. Some flimsy toilet seats are so thin, that you may not have enough material to drill into and use the supplied screws. Using very short screws as anchors, and using white silicone glue or caulk underneath and around the bumpers may be all that you can do. Also, the rubber bumpers may get squashed, and the metal screw heads can get pushed back enough to scratch the porcelain bowl (cover screw heads with caulk or silicone glue), -and the pointed screws can even crack the plastic or sawdust toilet seat. Unfortunately, there is another problem with elongated toilet seats. The front of the cheap modern elongated seats are flimsy plastic and not supported, -so the seat can flex and pinch you, -and even pull out a few short hairs when you go to stand up. These seats definitely need bumpers added to the bottom front of the seat. Finding old-style solid wood elongated toilet seats, or even very thick plastic toilet seats, is very difficult, so you are stuck with doing a little field engineering, to overcome the manufacturer’s lack of bumpers under the front of the toilet seat. This is the fourth most important part of my own toilet seat repair kit. See my own Amazon toilet seat repair kit at: Ginsey Home Solutions One Toilet Seat Tightening Kit, 1, Gray. Brand: Ginsey. Due to the lack of warning instructions, I only gave four Amazon Stars to this: White Silicone Toilet Seat Bumpers 7 Rubber Replacement Safety Bumper Caps Tips With Hardware For Toilet Bowl Protection Non Slip Shock Absorbing Seat.Very good quality toilet seat stops/spacers. A little pricey but worth the money. The soft silicone is very durable and keeps the seat from sliding or moving. The longevity should far outlast the toilet seat. They should be on all toilet seats instead of the cheap hard plastic ones that most manufacturers use.I had a wood toilet seat crack recently and decided that additional bumpers would distribute weight and stress better. But it did require drilling a bunch of holes and making sure not to drill through. These rubber bumpers are of good quality but thicker than Bemis original so not a perfect match. i think $20 for bumpers on top of a $35 seat makes for too much expense also. These are priced high but I guess better than the adhesive typeI got tired of buying the stick on one's that kept falling off into the toilet, so finally broke down and bought these. One tip, drill pilot holes before screwing in the screws.Me being 6 foot 6 and 300 lbs most seats will break. But with this product evenly spaced out it's a godsend. Just be sure to pre drill holes with a small drill bit! example..... few sizes smaller than the screws for easy installation.Did not receive the two smaller bumpers as advertised in the pack of 7. Only received the 5 larger bumpers plus all the screws. For the price I paid ($19.99), I would have thought they would have made sure all the parts were in the pack. Originally had gotten stick-on bumpers and those did not last even two weeks so decided I needed something better which I believe these will be. Only time will tell.Worked out perfect where our originals were broken off. Easy to install tooEverything was included, instructions were easy, pilot holes are always your best bet when screwing in to wood. FOr the uninitiated- don't make the pilot hole the same diameter as the screw threads!Placement is totally up to you and there really are enough bumpers for 2 john seats if you only need a little reinforcement. Or- you can go to town and seriously reinforce!These bumpers are a bit taller than the stock bumpers that came with the new seat. Not sure if that will allow for a bidet attachment, but we'll cross that bridge when we come to it.Thanks Renovator's Supply- you've always been a great place to shop!Debbe & Steve
