Perfect fit.
I had a fuse panel on an older boat that I needed to have new fuse holders for. These were a perfect replacement and worked great for me. I couldn't keep the fuses in the old ones anymore as the springs must have worn out so I was very pleased that these fit the panel perfectly and locked into place like they're supposed to.

Works with Both 1/4"x1-1/4" and 6x30mm Fuses
I bought this to replace a 5x20mm fuse holder rated at 15A, but got hot and lost 0.5+V at 10A. I tested this one and it held AGC/MDL, and 6x30mm fuses just fine. As others have written and Chinese influenced moron Amazon the fuse sizes are not the same. Some fuse holders can take both some cannot. It worked fine at 12V 10A with a 6x30mm SloBlo fuse (Chinese MDL semi-clone). 1/4" spade connectors held terminal fine as well. The plastic nut tightened down enough to smash the rubber gasket out. Had to readjust the nut to release the gasket. Overall, I am pleased with its performance.

Worked perfect for 12 volt cigarette plugs
My boat had limited space to work with on dash and needed a fuse holder that was serviceable after dash was buttoned back up and sealed. I added two 12 volt plugs and these with 10 amp fuses were the solution.

Nice fuse holder, perfect replacement for the older fuse holder on my Bridgeport Mill powerfeed.
Great little fuse holder. Although the retaining nut was missing, it may have fallen off at the Amazon warehouse, but I had the original nut from the old fuse holder and it was a perfect fit. Mounted within a few minutes, soldered the wires into position and I was back milling parts without an issue. Yes, I would recommend this fuse holder.

My experience with the one unit i have installed, was troublesome. Using 1-1/4" fuse
Installing the fuse holder was simple enough but putting the fuse in the socket was extremely difficult. I actually thought it "wasn't going to work"! It is a locking fuse holder and getting it to twist and lock was a challenge. It seemed like length tolerance was a bit off. Did not "feel" it lock in, but it stayed in and supplied power. This was just one device used, may not represent all.

Well built rated for 20a , I needed one for 15a, direct replacement, a little extra beef is good. Beware cheaper units as they are rated for less amperes. Perfect fit in 7/16" panel hole.

Excelente reemplazo para los originales. Fácil instalación y buena calidad del producto. Mi sistema eléctrico mejoro su confiabilidad ahora que ya no tengo falsos contactos por los portafusibles viejos.

3 way rv fridge cooked the original fuse holder ... as when it's on 12v ..the fridge draws at least 20amps! So ... most of the fuse holders are rated at that or below. You don't want to use it at the max continuously! Good product.
