The Faithfull Brick Line Runner is the fast and efficient alternative to traditional line blocks. Simply tie your line onto the line runner and clamp the unit over your working material using the spring-loaded jaws. The body is made from durable engineering plastic with a stainless-steel spring, making it weather-resistant and capable of withstanding on-site conditions. Suitable for use on materials between 90mm and 120mm. It also features anti-slip pads which firmly adhere to the surface of your working material. Ref: UTTK2276
