RollSafe Lockout Tool

Essential maintenance equipment for every fire-rated roll-up door

technology Snapshot

Overview

Fire-rated roll-up doors — the large metal doors used in industrial or secure facilities — are designed to automatically close when power is lost to contain fires. However, this same safety feature makes it dangerous and nearly impossible to perform maintenance on the doors while they are open. If power is turned off for safety, the door will automatically uncoil and close, creating a serious risk of injury or damage. Existing safety procedures and manufacturer options did not provide a way to keep the doors open safely without altering the door’s fire-certified design or risking damage to sensors and other components. RollSafe provides a simple, reliable way to keep fire-rated roll-up doors securely open during maintenance without compromising safety, compliance, or the door’s fire-certified design.

Advantages

RollSafe provides a simple mechanical lockout tool that attaches to the door’s axle to physically prevent it from closing when power is off.

  • It keeps the door safely open for maintenance.
  • It works with existing Lockout/Tag-Out (LOTO) safety procedures so workers can easily secure and tag the tool during repairs
  • It avoids modifying the door or voiding its fire rating.
  • It protects equipment and personnel, eliminating the need for unsafe props or energized work.
  • The tool design is durable, easy to install, and can be adopted commercially by door manufacturers as essential maintenance equipment.

In short, it transforms a previously unsafe maintenance task into a controlled, compliant and safe operation for anyone servicing fire-rated roll-up doors.

Technology Description

RollSafe Lockout Tool is a mechanical lockout device intended to secure fire-rated roll-up doors in the open position during maintenance and inspection activities. The invention addresses the inherent hazard created by these doors’ fail-safe behavior: When power is removed from the motorized operator, the door is designed to close automatically, which can make service work difficult or unsafe. RollSafe is designed to support maintenance operations while preserving the door’s fire-rated integrity and avoiding reliance on unsafe temporary restraints or energized work practices.

From a technical standpoint, the invention provides a purpose-built means of preventing unintended door movement during lockout/tagout conditions. It is positioned as a facility safety solution for industrial and secure environments where fire-rated overhead doors must remain compliant while still being serviceable. The broader value of the technology lies in converting a high-risk maintenance scenario into a controlled maintenance procedure without altering the certified door assembly.
