The revolutionary Allied Precision Industries LockNDry 25-Foot Indoor/Outdoor Power Supply Cord (4 Pack). Provides a weather-resistant seal while keeping the connection firmly secured. The specially designed plug on the LOCKNDRY cord fits any standard outlet, but when mated with a LOCKNDRY compatible power cord, the large black nut pulls the plug tight against the gasket to form a water-resistant seal. The red nut then locks everything in place and prevents cord separation. The LOCKNDRY is great as an all-purpose extension cord, too. It provides a secure, water-resistant electrical connection. It features a 16 gauge, 13 Amp Rating, 25-foot cord.
