I did a search but could not find this exact discussion. I' trying to find out what I need to comply with the following statement/rule "Parachutes shall be securely mounted to a suitable cross-member using an anchor that is at least 1 inch diameter or 1/2 inch radius". Wondering if I need to use a 1" bolt at the parachute tether to cross member or would a 1/2" bolt through a piece of 1" aluminum round stock be acceptable? I'm thinking the intent is the 1" material is required for tether retention and not just to ensure a large enough mounting piece so as to lessen the chance of cutting/tearing through the tether but as happens often, I could be wrong.
Any info/clarification that keeps me moving in the right direction is appreciated.

3.M PARACHUTE:
An approved parachute is required on all cars that qualify for the long course (175 MPH). Vehicles that exceed 300 MPH shall be equipped with two (2) independent parachute systems. Parachutes shall be securely mounted to a suitable cross-member using an anchor that is at least 1 inch diameter or 1/2 inch radius. All parachutes shall be opened during inspection. Special attention shall be given to the length and mounting point of the parachute tether line. The manufacturer’s recommendations should be followed regarding parachute size, mounting, etc.
On those vehicles required to have parachute(s), the deployment of the parachute(s) is at the driver’s discretion, consistent with safe and efficient event and vehicle operation.
Parachute failures, such as the parachute pack not opening, parachute canopy not opening, parachute separation from the vehicle, handling problems as a result of parachute opening, etc., will require a re-inspection.
ALL VEHICLES HAVING A PARACHUTE FAILURE SHALL RETURN TO THE INSPECTION AREA WITH ALL COMPONENTS OF THE PARACHUTE SYSTEM. A NOTATION WILL BE MADE IN THE VEHICLE LOG BOOK DESCRIBING THE FAILURE AND SOLUTION.
