Review on ⚡ Enhance Electrical Safety with Blue Sea Systems Block Insulating: Optimal Insulation for Securing Boating Electronics by Mike Carter

Replaced the car radio style fuse holder with this one so I could use spade lugs on all the power wires. I have used several other Blue Sea products in the past and they have really set the standard for wiring and installation quality. High quality materials at reasonable prices. Typical Blue Sea construction for this single fuse holder with quality hardware, durable material and easy installation. Much better than other types of holders. The lid is a bit stiff, so it looks like you'll break it when you take it off, but once you try snapping off the detachable tabs for a side-exit bracket, you'll see how long it takes for the plastic to actually break.
