TEC Accessories TEC-S311T
The TEC-S311T Isotope Fob is a keychain fob specifically designed to hold a standard 3mm x 11mm self-luminous tritium vial. Tritium vials come in a variety of colors, and will glow for many years without requiring any type of "charging" from sunlight. This version of Isotope fob is very similar to our longer TEC-S323 and TEC-S360 fobs, however it is shorter in length and has split ring holes at each end. This allows you to attach the housing between two items, or in tandem, such as your key ring and keys. You can then identify objects by color, such as your work keys and your house keys. And since the vials are short, the added length to your keychain items doesn't grow significantly and you also get the benefit of a lower price point. It's the perfect way to color-coordinate your items in a cost-effective manner!
NOTE: THIS PRODUCT DOES NOT INCLUDE A COLORED TRITIUM VIAL. Tritium vials are available here (size required is 3mm x 11mm).
Unlike our conventional line of glow fobs, the Isotope was designed around the use of a glass tritium vial. This makes it noticeably smaller than our standard glow fobs, and allows it to glow continuously without any type of charging cycle! The Isotope is a stainless steel housing, bead blasted to a uniform matte finish. There are 3 slots on each side of the housing to provide maximum tritium visibility, yet offers superior protection of the glass vial. Once the tritium is installed, you simply insert the included rubber plug (spares included) and attach the top split ring. This prevents the tritium vial from sliding out, yet provides an easy way to exchange vials if you want a different color.
Attach the TEC-S311T between your key ring and any attached item you wish to identify in the dark. You can clip it between a backpack zipper and flashlight, between one of our P-7 clips and a pocket tool, the uses are endless!
