The patented Steel Hawk 4300 Series is Adams Rite’s non-handed electrified deadlatch designed for aluminum glass storefront doors. The ANSI/BHMA Type E8231, Grade 1 Steel Hawk operates mechanically and electronically by releasing the deadlatching mechanism, permitting the latchbolt to retract as the door swings out from the jamb. Mechanically or electronically, the latchbolt is released, not retracted.
The latchbolt release mechanism can be freed three ways: by turning a key in the mortise cylinder counterclockwise until it stops, by rotating the interior handle or by powering the solenoid that controls the fail- secure locking mechanism.
The Steel Hawk 4300 Series eLatch incorporates the patented two-way winged technology by providing non-handed latchbolt operation for in and outswing doors without having to reverse the handing. The stainless steel latchbolt and the brass auxiliary bolt each have a two-part bolt. The latchbolt is 5/8” wide by 1” tall having a 5/8” throw. When the latchbolt and the auxiliary bolt are extended (door open), the wings are perpendicular to the door edge.
As the door closes and the latchbolt and auxiliary bolt contact the strike lip, one wing from each tilts over along side of the other forming a conventional “latch” shape and permitting them to retract into the 4300 eLatch as the door swings shut. Once the door is closed, the latchbolt slides into the strike plate cutout reforming the extended and rigid latchbolt. The auxiliary bolt remains partially within the eLatch. In the secured (closed) position, the auxiliary bolt prevents the latchbolt from being loided.
When the auxiliary bolt is retained, the latchbolt can only be unlocked by mechanically rotating the inside lever or paddle handle or by counterclockwise operation of the outside mortise cylinder.
Electronically, the Steel Hawk can be operated by powering the solenoid. Once the latchbolt is released, the door can swing open forcing the latchbolt against the strike plate. The latchbolt forms into a “latch” shape and retracts into the 4300 Series lock body, permitting the door to swing open. Once the strike plate is no longer in contact, the latchbolt and the auxiliary bolt extend.
The Steel Hawk eLatch is equipped with two Adjustable Mounting Tube Spacers screwed onto the 4300 frame at the top and the bottom. The threaded mounting tubes are adjustable in order to space the lock when using the drill and tap installation method. When properly adjusted, the mounting tubes fix the position of the eLatch. The Adjustable Mounting Tube Brackets are removed when installing the lock using bridges, brackets or tabs.
The mounted sample has a 4300 eLatch with a 1-1/8” backset and the new 4600 Deadlatch Handle equipped with the Adams Rite “MD” designer lever. The mortise cylinder requires an MS® (Adams Rite style) cam. The 4300 was installed into the mounted sample using two drilled and tapped 10-32 holes using the supplied mounting screws.
The 4600 Heavy Duty Designer Series Handle is manufactured of cast stainless steel, brass or bronze. There are eleven handle styles and seven standard finishes. Contact the factory for optional finish information. In addition to operating with the 4300 Steel Hawk eLatch, the 4600 Series Deadlatch Handle can operate with the 4500, 4900 and the DualForce 2190 and 2290 Interconnected Locksets.
The Steel Hawk uses an “MS” sized 1” x 6-7/8” faceplate. The faceplate is available as flat, radius or radius with weatherstrip. The flat faceplate is used with both a flat or beveled stile. The flat faceplate can be adjusted in the field for left or right beveled edge doors by rotating the spacers located above and below the latchbolt and auxiliary latch. Position each of the two triangle arrows in the direction of the bevel prior to installing the faceplate. For a flat stile, rotate the spacers having the triangle arrows pointing up or down.
An electrified lock such as the 4200 Series provides the opportunity to control access electronically without having to modify the door or jamb.
