Bussmann RTMR 15303-4-0-4 Mini Fuse & Micro Relay Power Distribution
Just got one of these with the proper terminals and seals. It is very nice looking and looks to fit mini and micro relays for 35 and 50 amp capacities, respectively.
Kind of regretting not getting the one with all the fuses bussed together on one leg, but that's life.
