Glossary: Fixations and Terminology
Diagonal
This is the tube that goes from the main hoop of the roll cage (drivers side) to the bottom of the opposite side backstay. This item is a key requirement for any Motor sport orientated roll cage. This diagonal can either be welded in place or be a removable bolt-in. If a passenger is carried during the events, it is advisable to have a double diagonal fitted (weld-in only) as this substantially increases strength on the passenger side too.

Harness bar
The horizontal tube attached to the back stays and the diagonal (if fitted). This provides extremely secure attachment for the harness shoulder straps (which are simply wrapped around) and negates the need to weld in additional fixing plates.
Saddle brackets
An original Safety Devices design which has stood the test of time. The bracket is used for connecting tubes on bolt-in cages. Much copied by our competition but beware as they often only use 3mm material which limits the torque setting of the bolts. Safety Devices has always used 5mm material.
Slipper tubes
A method of connecting tubes using sleeves and cross-drilled bolts. It is used on areas of the roll cage which require tube intersections of less than 90 degrees.
Boreham Arch Bracket
A multi point cage mounting bracket. Originally designed when Safety Devices prepared the Ford Escort shells for Ford Boreham in the famous days of Roger Clark. Produced in-house using press tooling.
Multi-point bracket
Similar multi-point brackets to the Boreham Arch bracket. Produced in-house using press tooling.
Tap pad
A bracket welded to the body shell to accept the bolt of a multi-point or Boreham bracket.
Gusset
Effectively 1 – 2mm thick sheet steel metal plates used to reinforce tube-to-tube tube-to-body shell connections.
Ears and squash ended tubing
Basically it means that the tube is pressed flat to produce a lug or fixing point. This is mainly used on 4x4 vehicles for roof diagonals and back stays.
