I have looked every where possible for these for a wall tent taut lines. I have found small ones, for parachute cord type thickness ropes. Need ones that can handle 5/16 rope. Not interested in those " figure nine types", etc. Classic oblong- rectangle with two or three holes fits the bill. Need about 20 of 'em.

Hope someone can steer me in right direction. Haven't had any luck on army surplus sites as of yet.
