Designed with open ends and a channel to allow for proper drainage.

Smooth rubber composition absorbs heavy loads without becoming sharp or abrasive, which helps to extend the life of your roof and eliminate additional maintenance typically required with wooden support blocks.

Durable yet gentle design requires no roof penetration or adhesion for installation.

Dampens vibration from AC equipment, so there is no need for additional rubber padding or noise reduction insulation.

14 gauge, galvanized steel channel is through-bolted on all sizes to maintain a high level of strength and weight capacity.

On longer assemblies, each block is spaced 1" apart to allow water to flow freely, preventing additional stress or the collection of stagnant water.

Reflective strip on each side provides clear visibility while helping to reduce roof-related accidents.
