Product Description

Title Line

Our Tool Release (TR) connector range is a popular way to add a layer of safety to applications where the connector is mounted very close to equipment that is rotating or spinning very fast, such as above rotary valves or rotary knives.

If you are still concerned about staff improvising tools to gain access to the TR hole, the TR LOCK-OUT SAFETY SYSTEM is the ideal solution.

  • A piece of elliptical tubing with a 7mm hole through both sides (the Lock-Out Tube) is welded over a Standard or Smiley-Face Tool Release hole on the top-ridge of a BFM® fitting spigot (where a Tool Release Connector is installed).
  • Any standard padlock (up to a 6.5mm shackle) can then be inserted through the top and bottom holes,  preventing unauthorized use of connector removal tools via the TR hole in the Spigot:

TR Lock-Out Safety System:

How Does It Work?

Title Line

A ‘TR Lock-Out’ Tube is welded to the outside of the spigot over the TR (Tool Release) hole in the top ridge of the BFM® fitting Spigot.

A padlock is then inserted through the hole in the sides of the Lock-Out tube, making it impossible to insert anything through the TR hole without removing the padlock.

This means that only authorized staff who hold the key or combination to the padlock can gain access to the TR hole to insert a Tool Release tool to remove the Connector.

TR Lock-Out Tube

Title Line

To install the system, a TR Lock-Out Tube is welded over a TR hole (a standard or Smiley-Face hole) on the top ridge of the Spigot.TR Lock-Out Tube over Smiley Face Hole

Extreme care must be taken when welding the Tube onto the Spigot to ensure no distortion of the top ridge of the Spigot occurs as this can affect the fit and seal of the BFM® fitting Connector.

We recommend the use of a heat-sink on the inside of the Spigot ridge during welding.
