Weld-in cage – General fitting instructions and tips

1. Check all the components of the kit and review the layout drawing as to the position

of each

• Locate the ‘B’ post hoop (main hoop) floor plate loosely in position and hold it place

with a piece of tape. (Picture1)

This plate position must remain flexible until the main structure of the cage is finished.

This plate position is the starting point of the original development and the starting

point for installation.

• The main hoop will require trimming to length. A black guideline is on each leg but the

height of the hoop will have to be made in relation to each individual body shell.

• Position the main hoop on the mounting plate, checking roof clearance etc. To hold

the hoop in place, tape the hoop to the roof to allow flexibility of movement.

2. Front legs and screen rail

• Loosely position the front leg plates and hold in place with tape (picture2).

• Check the fit of the legs with the ‘B’ hoop and profile the legs to fit against the ’B’

hoop. Each leg has a guideline marked on it (at both ends) tape legs in position

(picture 3).

• The screen rail should now be positioned and the same profiling of tube ends carried

out. If there is a roof diagonal in the kit, this must also be profiled and the whole

assembly check fitted at the same time. ( Picture 4)

• The fit and finish of this group of parts is paramount to the appearance of the cage.

Make Sure:

- The legs are close enough to the body to weld later and do not foul any other

components.

- The screen rail and roof diagonal are a good fit.

- The link to the front triangulation is good and the welder can get to all joints

easily. See section 4

• Now you are ready to do the final welding of the main structure joints.

- Weld the joints as much as possible.

- Remove the fitting plates from the ‘B’ post hoop and front legs

- Drop the cage down to the floor level. It may be necessary to pull the legs

together with a rope or ratchet strap. (Picture 5)

- Finish off the welding of the main structure on the topside of the joints.

- Lift the cage back into position and relocate the foot plates

- Shuffle the whole assembly to get the best fit in relation to the body. Tack the

cage to the body to hold it in position. DO NOT finalise the welding at this

point.

3. Rear backstays and other straight points.

• These can now be positioned. Many have the ends already profiled but may require

that to get a perfect fit are chamfered individually. Use a file or a die grinder to do this.

( Picture 6).

• Only when you have all the tubes tacked in place and are satisfied with the overall fit,

do you finally weld all joints including the floor plates and gussets.

• Use minimum weld lengths of 40mm when stitching to the body. Space them out

accordingly and symmetrically – Remember, good quality neat welding is very

important.

4. Front triangulation

• This usually requires a degree of skill in getting the fit to the cage accurate. The

triangulation will require to be in place prior to the front legs being finally positioned.

(Picture 7 & 8). The illustrations are with the outer panel removed. Use patterns

supplied to cut holes in the body.

Remember:

• Always check the clearance to other components as you progress with the assembly.

It is too late if for example you have finished the job and the seats foul!!.

Remember to send your certification to the M.S.A !!
