Atir Strap And — Beamd With 72 Install

The ATIR (Adjustable Twist Strut) is designed to laterally brace steel beams or joists to the structure. It creates a rigid connection to prevent rollover or lateral movement.

The term "72 install" refers to a standardized installation specification. Although not a universal building code number, it is commonly used in engineering details to denote: atir strap and beamd with 72 install

Most likely, in practice, “72 install” means: Use ATIR straps spaced at maximum 72 inches o.c. with 72 fasteners of specified type, installed according to the strap’s listed capacity.

In modern construction and seismic retrofitting, the synergy between tension-tie systems and continuous load paths is critical. Among the most reliable methods for connecting roof structures to wall framing is the use of the Atir Strap (often a proprietary or generic term for a heavy-duty galvanized steel tension tie) in conjunction with a bonded beam. When specifications call for a “72 Install,” they are referencing a specific, high-capacity anchoring protocol that demands attention to detail, precise fastening schedules, and adherence to engineered load values.

The number 72 is not a count. It is a phase angle and a time constant. The ATIR (Adjustable Twist Strut) is designed to

The BeamD-72 protocol is a proprietary, resonant installation method. Instead of mechanically clamping the ATIR Strap to the beam, an operator uses a phase-alignment tool (PAT) to emit a 72-hertz harmonic pulse. This pulse doesn't just attach the strap—it marries it to the beam's natural crystalline frequency.

The install process, known colloquially as The Sevens, follows three steps:

Measure 36 inches to the left and 36 inches to the right of the beam-to-post centerline (total 72 inches). Alternatively, the strap itself may be 72 inches long. Mark a reference line along the beam’s side where the strap will be seated. Installation Steps:
