Fire Strut-Lock


THE FIRE STRUT-LOCK SYSTEM utilises stainless steel wire rope to offer optimum performance in fire environments. The system can be used to construct lockable single or multi-tiered trapeze bracketry.

 

THE APPLICATIONS

SUITABLE AREAS OF USE INCLUDE, BUT ARE NOT LIMITED TO:

  • Installations to Edition 18 of the electrical wiring regulations.
  • Single-tier and multi-tier trapeze brackets.
  • Electrical and mechanical containment suspension.
  • HVAC installations/ductwork suspension.
  • Signage and displays.
  • Installations above fire escape routes.

AVAILABILITY

The Fire Strut-Lock system comprises a predetermined length of stainless steel wire from 1 m to 10 m, with a Safe Working Load of 90 kg per wire suspension in ambient conditions, and is supplied with the required Zip-Clip locking device. The system offers a choice of either pressed eyelet or pressed M8 × 35 male thread termination.

Note: Fire Strut-Lock is to be used only for static loads that are supported vertically. Always ensure the base material or anchor point are suitable to support the intended load.

 

Safe Working Loads

  • Y 90 kg

Fixing Options

The Fire Strut-Lock system is available with the following fixing terminations:

  • Pressed eyelet – to form choke knot.
  • Pressed male thread – M8.

 

Installation

 

Locating a Strut-Lock device into channel – building a single-tier trapeze bracket:

  1. Couple with square washer and channel nut.
  2. Position assembly into desired channel location.
  3. Tighten into position using a 17 mm spanner, turning clockwise.
  4. Back-off the locking collar and depress plunger. Do not undo fully.
  5. Insert wire rope through the plunger at the top of the device.
  6. Adjust the position by depressing the plunger and moving along on the wire.
  7. Once the trapeze bracket is in position, release the plunger and wind the locking collar up to the shoulder.
  8. Lock the trapeze position by turning the locking collar clockwise. Repeat steps 1 – 8 to build a multi-tier bracket.

Torque setting: It is recommended that the Fire Strut-Lock device is not over-tightened during installation. If it is possible to apply a torque value during installation, this should be no more than 15 Nm.

 

TO UNDO:

  1. Undo locking collar.
  2. Depress plunger.
  3. Reposition device to required height.
  4. Re-lock collar.

PLEASE NOTE: Load should always be supported before actuating the plunger and performing adjustment.

 

FIRE PERFORMANCE LOADINGS

Safe Working Load per wire suspension is 90 kg with a designed-in safety factor in ambient temperatures. Installations built with exact fire performance in mind must utilise the SWL for fire and use the correct amount of supports necessary to hold loads safely.
