Heavy Duty 4’ Rubber Dock Bumper for Boat Docks, Marinas, Loading Docks, and Parking Spots - 48" x 3" x 4"

I bought these to replace two old styrofoam pads that had completely deteriorated in the sun and weather. These bumpers I'm sure will out live me. They are very heavy duty and robust. I like them so much I have ordered 4 more. They take a little time to arrive but there are worth the wait. A word of caution during installation my DeWalt cordless drill just about went into the lake as I mounted them at the bottom of the wood. Turn your torque down to about 15 or16 when installing the 6" lag screws so your drill doesn't twist, break your hand and fall into the water.

These have worked great and held up for 2 seasons on our dock so far.

There is nothing better even for 3x this price. I've tried several others - inflatable, rubber, plastic. When you're done looking around, just buy one of these and you'll see. Some older reviews said shipping was slow, but they shipped mine out 2 days after I ordered. These are commercial grade hard rubber - like densely packed recycled tire rubber. It will last many years even when submerged in salt water . It's not soft. You can stand on it and it will not compress. They are designed to withstand heavy impacts. However, when I pushed my docked 41' boat into it, I clearly saw it compressing and adsorbing the shock. If you're looking for a soft bumper for a small boat, this may not be appropriate. You'll need 3/8" x 6" Galvanized or Stainless Lag Screws - you can buy them at a great price at: dockbuilders.com. You may want to consider the matching washers as well (they're not absolutely necessary, but the lag bolt head is not much bigger than the hole in the bumper). I recommend that you pre-drill the holes into the piling or wood to make it easier to screw in the lag bolts and to avoid cracking. I used a 7/32" bit, but a 1/4" might have worked better. You can also use some lubricant on the screws. You'll need a ratchet and Socket to screw them into the wood. Here is an installation technique: Pre-thread the bolts into the bumper with about a half inch protruding. Line up the bumper and mark it's location with a marker pen. Put the bumper aside. Measure down from the mark and drill the top pilot hole. Take the bumper and completely screw in the top screw. Now, screw in the other 2 bolts just enough to make a mark on the wood. With the bumper hanging on the top screw, pivot the bumper to the side and drill the remaining 2 pilot holes. Install the remaining 2 screws. It will be MUCH easier to align and screw in the lag bolts with pilots holes and a little lube on the threads will also help. Piling Facts: Bumpers are most important on rigid surfaces. Free Standing Pilings are not rigid - they have a great deal of give and are the safest things to bump. In fact, pivoting on them is a docking technique. But Pilings attached to docks and bulkheads are dangerous - they have no give. Bumpers are critical for these surfaces.

Very satisfied with the product except for one thing. It will leave a black mark on the boat when rubbing.

Works good very rugged

Installed with 6 inch galvanized lag bolts. Works great. It does have the specs listed, but it was heavier and bigger than I thought it would be. Each one weighs about 15 pounds. Another reviewer said it was a two person job to install. I did it by myself from my boat. My technique was to pre-thread a bolt into the "screw-hole", then adjust and duct tape the bumper in place and then install my pre-threaded bolt. Additionally, SHIPPING IS SLOW. My second order was just as slow as the first: Ordered on 6/23, shipping label created on 6/27 and then finally given to UPS [ground] on 7/2. Mine shipped out of NJ. So, don't be surprised if it takes TWO or more weeks for shipping.

Product is sturdy and appears to be a long lasting product. Going to use it as boat bumpers on a dock. Wife did not like the typical white boat bumpers, as they always look dirty, these might look good even with lake water hitting them.

Very heavy durable bumper. Not cushy. Great protection for the front of my pontoon boat and the slip.
