Rooftop support block with 3.5” roller stand
Simple to install, safe for most roofing materials, and vibration-dampening, the G-STRUT GRB300 series of rooftop support blocks supports a wide variety of pipes while allowing for lengthwise freedom of movement. These blocks use roller stands, available in a range of sizes, which clamp securely to the steel strut channel attached.
