Thule tour cycle carriers and square roof bars (Kenilworth CV8)
N.B. No keys but you can buy them off eBay for about £3 a pair 5 pairs needed as the carriers are not keyed alike but the bars are. Suffered a little damage to 2 of them as we had an arguement with an overhead bar in a car park once. Currently locked so I can't demonstrate with a bike. Three end caps missing.
