Swinging Jail Door Locks

The Problem with Swinging Door Locks 

Traditional swinging door locking systems in jails, prisons, and detention centers are frequently plagued by vulnerabilities due to age, damage, or design flaws, leading to compromised security. The standard installation approach of placing the lock in the frame and the strike on the door is prone to abuse and manipulation by the residents. This type of situation compromises the safety of residents and correctional officers, increasing the risk of inmate-on-inmate violence that could result in serious injury or death. Additionally, inmates can break Into other cells and steal or destroy property. 

Stay ahead of security threats and minimize liability risks by upgrading your locks with The Wedge®.

Willo's patented wedge locking system

The Wedge: Patented Platform for Maximum Security Detention Locks

This surface-mounted lock was designed as an alternative to standard swinging door installations. The Wedge platform consists of the patented double offset design, tamper alarm, and Gripper features to counter numerous manipulation attempts from inmates. 

The Wedge is tried and tested in jails and prisons all over the country, with correctional facilities confirming its effectiveness in various applications, including maximum-security needs. By preventing breakouts, this lock has created an environment conducive to maintaining safety, often boosting the morale of jail staff in the process. 

Delaying lock upgrades or choosing a system with fewer security features might seem like a cost-saving move, but if a compromised lock leads to an incident, your facility could face serious consequences such as code violations, legal action, and unexpected repair expenses.


The Wedge door closure

The Wedge

The Willo Wedge is more than a locking device. It is a comprehensive security locking system that strengthens facility security and protects both staff and residents. Offering a completely different level of protection than a standard Grade 1 maximum security lock alone, the Wedge upgrades your existing swinging door locks to a tamper-resistant locking system. It is custom engineered to the door, frame, and wall condition, ensuring a tight fit while eliminating common tampering methods.

The Wedge’s patented Gripper system encloses the latch bolt in a reinforced steel housing, which effectively blocks any attempt to access or manipulate the locking mechanism from the inside of the cell. The design counters common methods of tampering such as popping or sheeting the lock.

To further safeguard the facility, the Wedge includes a tamper detection system that immediately alerts staff with both visual and audible signals if anyone attempts to interfere with the lock. Officers can act quickly, often before a breach occurs. The system also features three-point monitoring that confirms the door is shut, the roller bolt is engaged, and the latch is locked. When all three conditions are met, a green light appears, giving officers confidence that the door is fully secure.

Here’s why The Wedge stands out from other jail locks:

Why is the Wedge Slim a must-have for new construction applications?

Willo’s newest innovation advances the traditional tamper-resistant features found in the original Willo Wedge, commonly used in renovation applications, and migrates them to the new construction environment.

Today, new prisons are built with the same wide-jamb, in-frame Grade 1 Maximum security locks that have been around for 30+ years. We know that these legacy designs exhibit vulnerabilities to safety and security of the staff and residents. Willo solved these issues with the introduction of the Wedge for renovation applications over a decade ago. The same security issues that generate the market demand for the Wedge in a retrofit application are the same reasons it applies in a new construction application. But rather than renovating, adding the tamper-resistant capabilities of the Wedge can now simply done at the time of construction.

When done at the time of construction, the Wedge Slim enables all stakeholders to take advantage of the existing construction process. In a typical renovation application, the existing DPS is abandoned in place, a new DPS is inserted into the Wedge, and the existing openings for the strike and door jamb are covered with cover plates. With the Wedge Slim, these steps are eliminated at the time of new construction. In addition, it’s designed to recess-mount inside the traditional lock prep, reducing the overall profile of the Wedge that would exist in an after-market application.

The Wedge Slim is uniquely engineered to apply to existing hollow metal manufacturers’ design without requiring changes to their traditional manufacturing process. The enables correctional facilities to capitalize on the patented tamper-resistant features to maximize security, while taking advantage of the new construction process, with a slimmer profile.
