Better by construction. Better by design

Pipe Saddle Design
Notched saddle-top for orderly piping alignment. Top trough aligns and cradles slotted steel strut channel for strut clamping systems and heavier loads.

Reinforced Screw Starter Guides
Indents allow for fast screw location for attaching clamps and straps. Internal structure increases screw-thread grip for added strength.

Install-from-the-Top Engineering
Easy installation and adjustment of height extension accessories — including 3/8" and 1/2" extension rods, roller brackets, and more — from just the top side.

Stable Design
Wide footprint for balanced weight distribution. Interlocking tabs allow end-to-end connection for wide applications including support for walkways and mechanical platforms.

Height Extension
Kit - (XTB-02)
Features pipe saddle-top design. Use with adjustable extension rods, or directly on top of Blox for 6" height requirements.

Securing Brackets
Pair of polycarbonate brackets provide anchoring to help withstand wind, water, and snow loads. Brackets mechanically lock onto Blox and permanently bond to roofing using
M-1 adhesive.

Protective Padded Base
High-density type-3 extruded polystyrene base cushions load to protect commercial roof membrane.

On-board Pipe Strap
Every Blox unit includes an on-board, galvanized clamping strap for securing up to 2" pipe.
