Tec-Accessories Isotope Triode Fob

The versatile TEC Isotope Triode Fob is designed to hold several glass tritium vials (not included), which will glow continuously for many years without the need to charge it from sunlight or UV light. This version of Isotope Fob has 3 individual bores to house the tritium, hence the nickname "Triode". The Triode can hold several combinations of tritium vials, as each bore can hold either one 3mm x 22.5mm vial OR two 3mm x 11mm vials. Think of the color combinations! The TEC Isotope Triode Fob has three primary bores to hold the tritium vials, and the six grooves on the side of the housing provide maximum tritium visibility, yet offers superior protection of the glass vials. Once the tritium is installed, you simply insert the included rubber plug (spares included), install the o-ring over the post, and attach the split ring. This prevents the tritium vials from sliding out, yet provides an easy way to remove the vials if you want to change or re-position the colors. Complete you
