Selling both new and used garage door springs for an old style wooden flip-up garage door. Our HOA got different doors so I'll never need these springs. Paid over $100 for two different spring sets and hooks while I figured out which ones worked best. Never been used pair of P728L 28" springs, two pairs of unopened C hooks, used P728 springs and C hooks that I only used for a year before the doors were replaced. All for flip-up doors only; won't work for roll-up doors. Buy everything together or willing to sell each pair separately.
