| Alley bumps were developed to address speeding and cut-through traffic specifically in alleyways. Molded bright reflective tape and high-quality cat’s-eye reflectors alert drivers well in advance. Channeled bottom facilitates cables and drainage. Available in 4’ and 6’ lengths, along with end caps to protect the alley bump ends and motorists. Alley bumps are designed for speeds of 1-5 mph. |
