Cover too loose.
Size: 300A Fuse Holder
Nice looking, decent quality, versatile for different gauges. My only complaint with this holder is the cover doesn’t stay on very well, bought 3, and all 3 pop off easily, you will need to zip tie on.

Rock-Solid Mounts with Flawless Adjustability
Size: Standard--black, Size: Standard--black
Absolutely fantastic mounts! I couldn't be happier with this purchase. They are currently holding my 12lb surround sound speakers on the wall, and I have complete confidence in their sturdiness. They feel incredibly solid and well-made. Installation was a breeze, and the range of motion is a real game-changer. Being able to swivel and tilt the speakers has allowed me to perfectly angle them towards my listening position, which has made a huge difference in my surround sound experience. On top of the great functionality, they have a very sleek and clean look. The built-in cable management is a brilliant touch that helps keep everything looking tidy and professional. If you're looking for a reliable, adjustable, and great-looking set of speaker mounts, look no further. These are top-notch, and I highly recommend them!
