Rubber Speed Bumps (MLSB)

Product Description

Our RubberForm MLSB Speed Bumps are effective permanent or temporary traffic calming devices such as check points and construction zones. They are carefully innovated to stay in place: no spikes, no lag bolts, and no adhesives are needed for temporary use. For permanent installation, use our lags bolt and shield hardware kits.

They’re easy to install, easy to relocate, and highly visible day or night. Our MLSB speed bump line are 100% American recycled masticated rubber that won’t crack, crumble, or corrode, no matter the heat, cold, rain, ice, or snow you throw at it.

Product Description

Most traffic calming methods are a huge pain. Concrete and asphalt speed bumps are difficult and time-consuming to install and maintain. They’re even harder to remove later when your needs change. They’re ugly, and when they chip, crack, and crumble (and they will), they stop working well–and somehow get uglier.

RubberForm MLSB Speed Bumps are blessedly easy and convenient. They’re simple to install and just as easy to remove or relocate later. If you do want to attach them permanently, you can. They’re fully modular, which means you can link them together to span any width needed. Their reflectors and safety reflective strips maintain high visibility at night, in fog, rain, or snow. They also come in variable heights, which means you can slow your target traffic down to as little as a stop to 3-5 miles per hour, or select a height designed to slow larger vehicles instead of personal vehicle traffic.

Our MLSB speed bumps are carefully innovated to withstand every possible environment you might want to install them in. They won’t melt in the searing summer sun or shatter in the frigid cold. They’re unaffected by rain, ice, or snow.  Our 100% American recycled masticated rubber won’t chip, warp, or spall either.

How are your speed bumps and speed humps anchored down?

We offer a lag bolt mounting system consisting of a lag bolt, anchor, and washer to anchor into pavement or concrete. There are 4 anchor holes for our MLSB product line in each speed bump. For temporary situations, you can just lay them down or moor them in place with our GRK’s RSS™ Rugged Structural Screw. For our RK Series speed bump and speed humps, there are 2 anchor holes for each 24” long section.

Can your speed bumps and humps be installed on a gravel road?

Yes, our MLSB traffic calming product line, with a 24” rebar spike or gravel earth screw can be purchased from RubberForm. These rebar spikes and earth screws should be checked periodically to make sure they have not crept up to create a hazard.

What is the reflective material on your speed bumps and speed humps?

For our MLSB2.5 we use 2 embedded AASHTO approved yellow reflectors. On our MLSB3 and MLSB4, we use a high visibility reflective yellow tape. For our RK series speed bumps and speed humps we use a special-formulated safety yellow paint with reflective glass beads.

Are these speed bumps removable, i.e., can they be moved to a new location or taken up for snowplows during the winter season?

Yes, if you need to remove them for the winter, just unbolt or unscrew the bolts/screws and store for the season. Seal the holes with Eco-Bond so water, dirt and rocks do not get lodged in the holes.

How long are your speed bump/speed hump sections?

Our line of MLSB speed bumps come in 36” long pieces that connect with a dovetail, allowing you to create the length you need. Our RK series speed bump and speed humps come in 24” sections that link together with a special dual-flange connector which also allows you to create any length you need.

What is the rubber material your speed bumps and speed humps are made of?

We have custom-formulated the right material for hard traffic over many years of use. We use masticated recycled rubber, which is harder and more durable than virgin clay-filled rubber or crumb rubber and poly compounds.

What is the turnaround time for your speed bumps and speed humps?

Our speed bumps and speed humps are in stock and can usually be shipped out the following day. Larger orders (greater than 100 units) may take a little longer - please provide us enough time to manufacture and let us know when you will need delivery.

Are your speed bumps and humps truly made in the USA?

RubberForm is one of the only true U.S. manufacturers of rubber speed bumps and speed humps. They are made from domestically sourced scrap tire rubber, manufactured, and assembled in the U.S. We believe that this is the only way to maintain our high standard of quality control.
