Speed bumps, despite their humble design, are well-suited to the task of serving as traffic calming devices. Simply add one to your parking lot or construction site, and then just sit back and watch the oncoming vehicles reduce their speed as they approach! Transline Industries carries both plastic and rubber speed bumps as part of our normal product catalog. Our Plastic Speed Bumps are manufactured from post-consumer and post-industrial recycled plastic. Designed with safety and durability in mind. Flexible enough to fit parking lot contours, yet rigid enough to withstand repeated abuse from cars and trucks. Constructed with high-density polyethylene for weather, UV, and chemical resistance. Speed Bump/Cable Protector is available in high visibility yellow.
