Zero 656A 72IN Threshold, 72in, Aluminum

Zero International Inc 656A 72IN Threshold offers a premium solution for enhancing energy efficiency and creating a robust barrier against smoke, sound, and light. Crafted from heavy-gauge aluminum, this 72-inch threshold is designed to withstand the rigors of high-traffic openings and extreme temperature differentials, ensuring durability in commercial and institutional settings. One of its standout features is the energy-efficient thermal-break design, which effectively prevents the transfer of outside temperatures and frost to the interior side of the door. The adjustable-width system allows for easy installation with threshold rests that interlock with various size plates, eliminating the need for exposed screws for a cleaner appearance and enhanced stability. Additionally, the extruded bulb finger (EBF) double sealing system guarantees an airtight seal, even if doors are slightly misaligned or warped. This innovative design includes a supplemental "finger" in the neoprene gasket, effectively blocking airflow to maintain a comfortable indoor environment. Available in multiple finishes, including aluminum mill, black anodized, dark bronze anodized, gold anodized, architectural bronze, and oil-rubbed bronze, the Zero 656A 72IN Threshold combines functionality with aesthetic versatility, making it an excellent choice for both interior and perimeter applications.

Threshold, 72in, Aluminum

From increasing energy efficiency to creating a barrier for smoke, sound and light – thresholds serve many important purposes. That’s why it is important to standardize on top quality materials and construction. Zero thresholds are designed to stand up to the demands of heavy traffic openings and those with extreme temperature differentials. The heavy-gauge material allows you to drill and screw our thresholds directly into concrete without the difficulties common when using lighter commercial materials, such as buckling under heavy loads or loose screws. Commercial and institutional facilities can benefit from using ZERO for both interior and perimeter applications.

Features:

• Energy-efficient thermal-break thresholds – Specially designed to prevent the transfer of outside temperature and frost to the interior side of the door
• Adjustable-width systems – Features threshold rests that interlock with various size plates. Much easier to trim and fit than conventional, single-size cast-bronze thresholds. Install without exposed screws on the base for better aesthetics and durability
• Extruded bulb finger (EBF) double sealing system – Designed to ensure an airtight seal even when doors are misaligned because of poor installation or slightly warped. If the door fails to make contact with the bulb in this neoprene gasket, the extra "finger" acts as a supplemental seal to block air flow

Finishes:

• A - Aluminum mill finish
