Flip Lever Upgrade to the Ultimate Astragal - November 2010

Endura Products is now releasing the unique, performance tested, Flip Lever Upgrade to the Ultimate Astragal. The elegant, single-stroke, flip lever action secures the top and bottom flush bolts in one smooth motion. 

When the Flip Lever is engaged, the Flush Bolt Sleeve Assembly, incorporating the patented Ultimate Astragal 3 Point seal, first moves to mate with the sill and header. Subsequently, a full throw of the Flip Lever brings the bolts themselves to meet the depth of the flush bolt retainers no matter how deeply they are drilled. This eliminates the need for separate flush bolt mechanisms at the top and the bottom of the Ultimate Astragal for enhanced accessibility. 

An additional feature incorporated in the Flip Lever Upgrade is the enhanced security. As the flush bolts are part of an integrated assembly driven by the flush bolt, and independent of the bolt sleeve, the flush bolts cannot be pried open without operating the Flip Lever Assembly.

The Flip Lever upgrade is now available for order. For more information about Endura’s line of door component systems, please call 1-800-334-2006 or visit
