The kit includes one pair of rung lock assemblies (left and right sides), replacement springs, mounting bolts, and hardware - everything required to restore full rung lock function to your ladder. Rung locks are the spring-loaded mechanisms on extension ladders that automatically engage the rungs of the base section when you extend the fly section. They are what holds the ladder extended at your working height. When rung locks wear out, they may fail to engage properly, engage weakly, or release unexpectedly - all dangerous conditions that can cause the ladder to collapse. For gutter contractors who use extension ladders daily, rung lock wear is inevitable. The constant extending and retracting, exposure to weather, and debris accumulation all contribute to rung lock degradation. Rather than replacing an entire ladder when the rung locks wear out, this repair kit allows you to restore full safety function at a fraction of the cost. The kit fits Louisville extension ladders that use this rung lock style - check your existing rung locks against the images to verify compatibility before ordering. Installation requires basic hand tools and can typically be completed in under an hour.

Check rung locks before each use - they should engage firmly with a solid click and hold the fly section without any slipping. Any hesitation, slipping, or unusual noise means the ladder should be taken out of service until the rung locks are replaced. The cost of a repair kit is far less than the cost of an injury.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #e3f2fd; border-left: 5px solid #2196f3; padding: 15px; margin: 20px 0; border-radius: 5px;\"\u003e\n\u003ch4 style=\"color: #1565c0; margin: 0 0 10px 0;\"\u003eHow Rung Locks Work:\u003c\/h4\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eExtension ladder rung locks consist of a pivoting bracket with a spring-loaded pawl (hook). When the fly section is raised, the pawls are pushed inward by the rungs passing by. When you stop raising and release the rope, the springs push the pawls outward so they catch on the rungs below, locking the fly section in place. The weight of the fly section and the person on the ladder presses the pawls firmly against the rungs, creating a secure lock. To lower the ladder, you pull the rope, which lifts the fly section slightly and allows the pawls to disengage. The rung lock mechanism experiences significant stress with each use - the pawls strike the rungs during extension, bear the load when locked, and must overcome spring tension during retraction. Over hundreds or thousands of cycles, the pawl edges wear smooth, springs weaken, and pivot points develop play - all of which reduce the security of the lock.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #e3f2fd; border-left: 5px solid #2196f3; padding: 15px; margin: 20px 0; border-radius: 5px;\"\u003e\n\u003ch4 style=\"color: #1565c0; margin: 0 0 10px 0;\"\u003eKit Contents - PK100D Rung Lock Repair Kit:\u003c\/h4\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; font-size: 14px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background: #1a3a5c; color: #fff;\"\u003e\n\u003cth style=\"padding: 10px; text-align: left;\"\u003eComponent\u003c\/th\u003e\n\u003cth style=\"padding: 10px; text-align: left;\"\u003eQuantity\u003c\/th\u003e\n\u003cth style=\"padding: 10px; text-align: left;\"\u003eFunction\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background: #f8f9fa;\"\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold;\"\u003eRung Lock Brackets\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2 (Left and Right)\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eMain mounting plates that attach to fly section\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold;\"\u003eLocking Pawls\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eHook pieces that engage the rungs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background: #f8f9fa;\"\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold;\"\u003eCoil Springs\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eProvide tension to push pawls into locking position\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold;\"\u003eMounting Bolts\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e4\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eSecure brackets to ladder rails\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background: #f8f9fa;\"\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold;\"\u003eHex Nuts\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eSecure mounting bolts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp style=\"margin: 15px 0 0 0; font-size: 14px; background: #fff; padding: 10px; border-radius: 5px;\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This kit includes all hardware needed to replace both rung locks.

The kit contains replacement rung lock brackets, locking pawls, springs, bolts, and nuts - everything needed to restore full rung lock function. Rung locks are the critical safety mechanism that holds the fly section extended; worn or damaged rung locks can cause sudden ladder collapse. This genuine Louisville repair kit restores safe operation at a fraction of new ladder cost. Installation requires basic hand tools.
