   high quality FD20 connector


ShoppingQueen2023  2026-02-03

Great product! High quality and works perfectly. Fast shipping and well packaged. Highly recommend!
   Clean IP68 waterproof flange mount for outdoor electrical boxes


HealthyEatsShopper  2026-02-02

The FD20-F flange mount fit perfectly into our outdoor electrical box. The IP68 waterproof seal kept moisture out all winter, and the screw terminals made wiring a breeze. Looks professional and holds up to the elements.
   Perfect for low-power outdoor sensors & LED strips


TidyHomeFanatic  2026-02-02

These FD10 waterproof connectors are the perfect fit for my low-power garden sensors and LED strip lights. The IP67 rating kept everything working through weeks of rain, and the snap-lock clips hold tight even in wind. Installation was super quick with screw terminals—no soldering needed.
   Finally a tiny waterproof connector that works!


BeautyBuzz2023  2026-02-02

Tried cheap alternatives for my LED strip lights—they all failed in rain. This FD10 IP67 connector locks tight, installs fast with screw terminals, and my outdoor lights stay on perfectly. No more wasted money!
