Review on 💪 High-Quality InstallGear 0/2/4 Gauge Ga ANL Fuse Holder with 300 Amp ANL Fuses (2 Pack) - Superior Protection for Your Vehicle's Electrical System by Reynaldo Guzman

This is a better quality fuse holder than most cheap built in holders which normally use AGU fuses. An ANL fuse is more reliable, and screw terminals work best for holding the wires securely. It was a bit larger than I expected, with my caliper it measures 124mmL x 38mmW x 37.4H and the wire holes are about 20mm x 20mm, enough room for my 4 AWG wires. I would recommend being careful not to fall out the small pieces of plastic on the bottom as another reviewer mentioned. If they fall out before you install the fuse holder, it may cause a short circuit. Overall great, especially for the price!
