The ABH 1858 Universal Bottom Fire Bolt is a premier solution for both wood and metal doors, offering essential thermal fire protection without the need for floor preparation. Designed for seamless integration with manual top bolts (model 1855S), this bottom fire bolt ensures reliable performance in high-stakes environments. The bolt’s innovative thermal activation feature melts the plug and black plastic cover at 230°F, allowing the bolt to project and securely lock the leaves together, providing enhanced fire safety.
Constructed from durable stainless steel, the ABH 1858 delivers outstanding strength and longevity, making it suitable for heavy-duty applications. Its bright bronze finish not only enhances its aesthetic appeal but also offers protection against corrosion and wear. This universal design allows for versatile application across a variety of door types, ensuring compliance with safety standards.
While the 1858 model is UL listed only when used with an automatic top bolt, it remains an essential component of any fire-rated door assembly. With additional custom finishes available, this product is tailored to meet the specific needs of architects, contractors, and facility managers looking for dependable fire safety solutions.
