Key specifications

Choosing the right option

Choose the sleeve by the diameter of the wire, not the cable's rating: 3.18mm sleeves fit 1.17 to 2.79mm wire (22 to 16 AWG), 4.75mm fit 1.57 to 3.81mm (20 to 10 AWG), 6.35mm fit 2.39 to 5.46mm (16 to 8 AWG) and 9.53mm fit 3.18 to 8.13mm (12 to 4 AWG). Then choose the cartridge: M4 cartridges (19.05mm wide) and M5 cartridges (25.4mm wide) hold 80 die-cut sleeves, and M4C cartridges are continuous so you cut each sleeve to length.
