Common closer problems
A closer can lose tension, leak fluid, pull loose from the frame, or be adjusted so far out that it never latches correctly. Wind, heavy use, and misaligned storefront doors can make the same closer problem come back if the door itself is not checked.
Why latching matters
A door that looks closed but has not latched can leave a shop, office, or back door unsecured after hours. The repair may involve closer adjustment, arm position, mounting screws, hinge wear, latch alignment, or hardware replacement.
