ARC have these extremely user friendly parachute chassis brackets in stock. They are laser cut and CNC folded from 5mm mild steel. The large hole in the rear flange accepts 1 1/4" tubing, whilst the bolt hole is 1/2" to meet ANDRA regulations. The clear span between the side webs is 50mm. The spindle is manufactured from 5083 aluminium and is available with the bracket as a package, or can be purchased separately. The minor diameter is 1" to meet ANDRA regulations and features a taper each side up to 30mm diameter to keep the tether centred to help reduce chafing.
