Every professional lighting system is only as reliable as its weakest splice. That's why FX Luminaire's WCHSMD20 heat shrink wire connectors are designed to provide contractors with a secure, waterproof, and direct burial-ready solution for low voltage connections. This 20-pack of medium connectors supports typical landscape wiring setups, including two 10 AWG or three 12 AWG conductors. Each connector features an internal metal barrel for solid contact and integrated strain relief, surrounded by adhesive-lined heat shrink tubing. When heat is applied, the tubing seals tight around the cable while the adhesive bonds to the jacket, forming a permanent, weather-resistant barrier against moisture, soil, and shifting terrain. Built for speed and dependability, WCHSMD20 connectors eliminate the need for crimp tools, junction boxes, or complicated splicing methods. Whether you're making home run terminations, extending fixture lines, or repairing existing installs, these connectors ensure every connection is done right the first time and built to last.
