The Emtek F20 Mortise Lock Screw: A Comprehensive Guide

The Emtek F20 Mortise Lock Screw is a heavy-duty security lock that provides more robust protection than a standard cylindrical lockset. It is suitable for doors with a thickness of 1-3/4 to 2-3/4. The lock features a deadbolt operated by a key on the outside and a thumb turn on the inside. When the deadbolt is engaged, the outside knob is automatically locked, and the latch bolt can be retracted by a thumb press on either side, except when locked by the stop button. The inside knob retracts the latch bolt and deadbolt simultaneously, with the outside knob remaining locked. The lock also includes anti-pick security features and a 180-minute fire rating.

Screw pack for rosette, strikeplate, faceplate, etc

The screw pack for the Emtek F20 mortise lock includes all the mounting screws you need to install the rosette, strikeplate, faceplate, and other components. The pack ensures a secure installation, providing screws that are specifically designed for each part of the lock. This comprehensive pack eliminates the hassle of searching for individual screws and guarantees a proper fit for your Emtek F20 mortise lock.

Meanwhile, the strikeplate and faceplate screws ensure the robust attachment of these components, which are essential for the lock's functionality and aesthetics.

Additionally, the screw pack includes screws for mounting the lock to the door itself, ensuring a sturdy installation. This comprehensive pack streamlines the installation process, providing all the necessary hardware in one convenient package.

Emtek's attention to detail extends beyond their lock mechanisms and elegant designs. The inclusion of this screw pack showcases their commitment to providing a complete, high-quality product that simplifies the installation process for professionals and homeowners alike.

UL180-minute fire rating

The Emtek F20 Mortise Lock has a UL180-minute fire rating. This means that the lock has been tested to ensure that it meets high safety standards and can withstand a fire for up to 180 minutes.

The UL180-minute fire rating is a feature of both the F20 and F13 functions of the Emtek Mortise Lock. The F20 function includes a mechanism to temporarily override the outside lock, which can be activated by pressing the release button. The lock also features a stop button and a heavy-duty lock body.

The F13 function, on the other hand, operates as a standard keyed lock and does not include a stop or release button.

Both functions offer a UL180-minute fire rating and are UL Listed Mortise Door Prep ANSI A115.1. This means that they have been rigorously tested to meet the safety standards of Canada and the United States and are suitable for use in commercial buildings.

The Emtek Mortise Lock is a heavy-duty lock that provides a range of locking options and is suitable for the finest homes. It includes a deadlocking latch bolt and forged deadbolts with anti-saw inserts for added security.

Dummy sets for double-door appearance

Dummy sets are a great option for double doors to achieve a uniform look. When ordering handlesets for double doors, remember that handlesets are not sold as pairs, so you will need to order two handlesets: one for the active side and one for the inactive side.

For a left-hand active door, you will need to order one left-hand single-cylinder handleset and one right-hand dummy function handleset. Conversely, for a right-hand active door, you will need to order one right-hand single-cylinder handleset and one left-hand dummy function handleset. Dummy handlesets are very similar to active sets in terms of construction and typically cost the same or slightly less.

Dummy sets are available in a variety of styles and finishes to match your door and decor. For example, the Delaney Hardware Italian Collection offers dummy handlesets in black, satin nickel, and bronze with different interior options like the Artino, Florini, and Santo. Schlage also offers dummy handlesets in satin nickel with glass door knobs.

Dummy sets are also available for Emtek mortise locks. Emtek's F20 mortise lock function provides more locking options with its Stop and Release buttons. The lock is operated by a key from the exterior and a thumbturn from the interior.

Emtek's brass mortise lock trim

The latch nose-bolts, strike plates, and faceplates of Emtek's brass mortise lock trim are also made of solid brass. The threaded tubes inside an Emtek lock are machined brass, ensuring good threads and preventing corrosion.

Emtek lever door handles have a fixed stop at the top of their stroke, allowing them to rotate downward only. This is in contrast to most products on the market, which rotate up-and-down. Emtek door knobs and lever door handles are supported by springs behind the rosette or backplate, actively returning the door handles to their original "rest" position to prevent sag.

A plastic bushing is located in the joint between the handle and the rosette, ensuring a friction-free wear surface. This prevents metal from bearing on metal and provides smooth, long-lasting operation. The handles are connected to the rosettes and backplates with a permanent clip, and each handle has a set screw. When tightened, this screw eliminates any wobbling of the door handle.

Installation by a professional

Emtek mortise locks are available in two different function types: F20 and F13.

Emtek brass door handles are hand-buffed for maximum polish.

Emtek lever door handles have a fixed stop at the top of their stroke so that they only rotate downward, not up-and-down. Emtek door knobs and lever door handles are supported by springs behind the rosette or backplate that will actively return the door handles back to their original "rest" position to prevent sag.

A plastic bushing located in the joint between the handle and the rosette ensures a friction-free wear surface, preventing metal from bearing on metal and providing smooth, long-lasting operation.

Emtek's single cylinder mortise handlesets use traditional American mortise locks complete with a variety of trim styles, handcrafted from authentic materials. The mortise lock is operated by a key from the exterior and a thumbturn from the interior. The door is opened from the exterior by a metal handle with a thumb grip and by your choice of a variety of knob and lever options from the interior.

These locks are uncompromisingly rugged and beautifully crafted, suitable for the very finest homes.
