Probrico Square Deadbolt, Flat Black, Different Key Set for Interior and Exterior, 1 Pack

The Matte Black Series, Brushed Nickel Series, and Oil Rubbed Bronze Series door handlesets and deadbolts are part of the brand's offerings. These products are suitable for standard doors and can be unlocked or locked from both sides using a key, with the keyway being Kwikset.

The deadbolts are designed to fit doors with a thickness ranging from 1-3/8 inch to 1-3/4 inch (35mm to 45mm) and feature a double-cylinder design, providing higher security. This can be particularly useful in restricting indoor personnel, such as children, mentally ill patients, and those engaged in confidential work, from leaving the room at will.

The adjustable latch can accommodate door frames with a 2-3/8" or 2-3/4" (60mm or 70mm) backset. Each box includes the deadbolt exterior, deadbolt interior, adjustable latch, plastic cover, strike plate, short screws (ST420mm), long screws (M435mm), an Allen wrench, and three keys.

The installation process is straightforward, with four easy steps: 1. Install the latch, ensuring the door punching diameter is 54mm (2.125"). 2. Install the exterior and interior hardware, remembering to remove the internal lock cylinder first. 3. Use the Allen wrench to tighten the square cover. 4. Install the plastic box and strike plate, which can be done as the first or last step.

The brand offers various deadbolt options, including Square Single Cylinder Deadbolt, Square Double Cylinder Deadbolt, and Round Double Cylinder Deadbolt, in different finishes such as Matte Black, Brushed Nickel, and Oil Rubbed Bronze.

The products have received positive customer reviews, with ratings ranging from 3.5 to 5.0 out of 5 stars. The Double Cylinder Square Deadbolt with a different key and a black finish is specifically mentioned, featuring a 65mm square panel and a stainless steel body.

The universal latch can accommodate door thicknesses from 1-3/8" to 1-3/4" (35mm to 45mm) and a backset of 2-3/8" or 2-3/4" (60mm or 70mm). The zinc alloy deadbolts are easy to maintain and designed to last for years, providing high security for your home.
