ABH 019 Heavy-Duty 3/4" Offset Intermediate Pivot | US32D Satin Stainless Steel

The ABH 019 is an architectural-grade 3/4" offset intermediate pivot designed to provide critical alignment and structural support for tall or heavy commercial doors. Engineered for use with 3/4" offset pivot sets, this intermediate hinge is a vital solution for door restoration that prevents the "bowing" or warping often seen in oversized door leaves. Crafted from high-strength stainless steel with a sleek US32D Satin Stainless finish, the 019 model is a premier solution for commercial door security in institutional environments like schools, hospitals, and high-traffic office buildings.

Essential Alignment for Tall Commercial Doors

Standard top and bottom pivot sets are often insufficient for doors exceeding standard heights. The ABH 019 serves as a proactive solution for door surface repair by maintaining the door's vertical plane:

• Strategic Weight Support: For doors above 60" tall, one intermediate pivot should be installed in the center of the opening. An additional pivot is required for every additional 30" of door height (e.g., a 90" door requires two intermediate pivots). This prevents the door from sagging toward the lock side and ensures consistent latching.
  
• Maintains Door-to-Frame Alignment: By reinforcing the middle of the door, the 019 helps maintain a uniform weatherseal and prevents the door from rubbing against the jamb—a common cause of hardware failure.
  
• Full Mortise Installation: This pivot is designed to be completely mortised into the side jamb and the hinge edge of the door, providing a clean, concealed look that supports a modern architectural aesthetic.
  
• Precision Smooth Operation: Equipped with heavy-duty stainless steel needle bearings, the ABH 019 ensures fluid, friction-free movement even under the stress of heavy use.
  

Built for Safety and Structural Integrity

To meet the demands of modern fire codes and high-use facilities, the ABH 019 is built to the highest industrial standards:

• 3-Hour Fire Rated Protection: This intermediate pivot is UL Listed for use on fire-rated doors up to 3 hours, ensuring your facility remains compliant with life safety regulations.
  
• Architectural Stainless Steel: The US32D (630) finish is not only aesthetically pleasing but also provides a durable, corrosion-resistant surface that stands up to harsh cleaning agents and high-humidity environments.
  
• Stability with Thru-Bolt Security: For maximum stability, it is recommended to install this hardware using thru bolts (available separately) to create a reinforced "clamping" effect, providing a permanent solution for door edge reinforcement.
