Revolving Door Drop Bolt

The Progressive Hardware R1000DU is a gravity-operated drop bolt designed originally for revolving door installations. It suits commercial entrances where a mortise-mounted deadlock is required and a simple 90-degree key turn is preferred.

Bolt Projection and Case

A stainless steel bolt extends 1-9/16 inches from a solid aluminum case measuring 5-7/8 by 1-3/4 by 1 inches. The 5/8-inch round bolt drops by gravity when the key is turned, providing a positive mechanical lock without spring assistance.

Mortise Cylinder Integration

The lock accepts a standard mortise cylinder and ships with a Yale 1 Key Way cylinder plus two keys. Installers must prepare a mortise pocket matching the case dimensions; the Duranodic finish coordinates with common aluminum storefront systems.

Questions about this item

Will the 5-7/8" x 1-3/4" x 1" aluminum case fit the mortise pocket I already have in my door?

The case measures 5-7/8" x 1-3/4" x 1". Compare those dimensions to your existing pocket before installation.

How do I confirm the stainless steel bolt is engaging correctly after fitting the lock?

Turn the key 90 degrees; the 5/8" round bolt should drop by gravity and protrude 1-9/16" into the strike.

Does the package include the cylinder and keys, or do I need to order a Yale 1 Key Way cylinder separately?

A cylinder and two keys are included, so no separate cylinder purchase is required.
