Product Details
Setting up rooftop loads is easier than ever with the GRB101, because the channel is built right in. The galvanized steel strut uses standard fittings and clamps, while the 100% recycled rubber tire base block is compatible with most rooftop materials. Plus, vibrations are dampened, reducing damage to your roof as well as decreasing sound.
