Many trappers have asked for a lighter weight and a lighter pull In-line Shock Spring. Sleepy Creek's 56 lb. pull In-Line Shock Spring with tempered cupped slides is now available. The long spring applies a softer light load while the shorter spring takes the lunge of a heavier critter. The mis-shaped slides help prevent rust from locking them. For those who wish an even lighter assembly, remove the short spring for a 40 lb. version. Designed to be setup with double swivels and "J" hooks (not furnished).
