The original grab straps consisted of a stiff backing covered by a beige or red patterned material which was attached to a chrome plated bracket. The bracket was then screwed to the door pillar. See page 193 of David Lawrence's book 'Let there be Y's' for more information.
These reproductions are hand made and covered in the beige coach lacing material used to cover the door seals. They have a tough canvas inner and come complete with a chrome plated brass reproduction loop bracket (that we also sell separately) and two polished, stainless steel self-tapping screws. Don't forget that you need to order 2 Grab Straps for each car.
