4 position fuse socket for 3AG size 1.25" x 1/4" (6.3x32mm) glass or ceramic fuses. These snap apart for custom installations. Great replacement for old worn out fuse holders on games like Pacman (6 each), mechanical pinball machines of any age, GO-7 monitor repairs, etc.. Has 1/4" push-on terminals or they take solder very well. Most of the other holders' sold are very hard to solder.
