This is a group of four new, old stock, Best Lock/Best Access padlock throw members and spacers. They operate Best padlock models 11B, 21B and 41B.Included in the group are two throw members that are key retained and two are non-key retained. If you are not familiar with the key retained throw members, they prohibit the key from being withdrawn when the padlock is unlocked and provide an added degree of security. Also included are four spacers that allow the use of a 6 pin core in 11B, 21B and 41B padlocks. Here is your opportunity to obtain Best throw members that give your padlocks extra flexibility. Please check out our ebay store for other Best Lock items. Please note: Due to the age of these throw members, there may be slight age spots (natural patina) on some of them.
