One End Cap. Two Functions from the Same Tool.
The TSB-ENDCAP is a machined glass breaker tip that threads onto the base of Safety Technology’s TSB-series telescopic steel batons. If you already carry one of the compatible models — the 16″, 21″, or 26″ rubber-handle batons — this end cap adds a vehicle escape function without requiring a separate tool on your belt or in your bag.
The fit is threaded, not friction-based, so it stays in place under normal carry and deployment conditions. Installation takes a few seconds. Removal is equally simple when not needed.
Who This End Cap Is For
Security officers and first responders who already carry a TSB-series baton. In vehicle accidents or confined emergency situations, the ability to break a window quickly can determine outcomes. Adding this end cap costs under seven dollars and requires no additional training or carry space.
Drivers who keep a baton in their vehicle as a defensive tool. The same baton that serves one purpose on the road can serve a second purpose in an accident — if it’s equipped for it. The end cap makes that possible without changing how the baton carries or handles during normal use.
Anyone who values functional redundancy in their gear. A tool that does two jobs reliably is more useful than two tools, especially in situations where access to equipment is limited or time is short.
Is This the Right Choice for You?
Choose this end cap if you want:
- To add glass-breaking capability to a baton you already own and carry
- A vehicle escape option integrated into existing gear rather than a separate tool
- A low-cost upgrade to a compatible TSB-series baton
Consider something else if you need:
- A standalone glass breaker — this requires a compatible TSB-series baton to function
- Compatibility with other baton brands or models not in the TSB-16R/21R/26R line
What the End Cap Does and How It Works
Tempered glass — the type used in car side windows — is designed to shatter into small pieces under a focused point strike. A blunt impact distributes force across a wider area and often won’t break the glass cleanly. A hardened pointed tip concentrates force at a single contact point, which is what causes tempered glass to fail at low impact force relative to its overall strength.
The TSB-ENDCAP provides that focused point at the base of your baton. In a vehicle emergency where door mechanisms fail or power windows won’t operate, a firm strike to a lower corner of a side window with the pointed end cap will shatter the glass and create an exit. The lower corners are the structurally weakest point of a tempered side window and require the least force to break.
The end cap’s threaded design means it doesn’t work loose during normal baton handling. It adds 0.2 lbs to the overall baton weight, which is a negligible change to balance and swing characteristics. The black finish is consistent with standard TSB-series coloring.

Practical Details
Color: black. Weight: 0.2 lbs. Threaded screw-on installation — no tools required. Compatible models: TSB-16R (16″ rubber handle baton), TSB-21R (21″ rubber handle baton), TSB-26R (26″ rubber handle baton). Not compatible with other baton brands or non-rubber-handle TSB variants. Verify your baton model before purchasing.
If you carry a compatible TSB baton, this end cap is a straightforward upgrade — vehicle escape capability integrated into a tool you’re already carrying, for under seven dollars.
Frequently Asked Questions
How do I know if my baton is compatible?
The end cap is compatible with three specific models: TSB-16R, TSB-21R, and TSB-26R. These are the rubber-handle telescopic steel batons in Safety Technology’s TSB series. The model number is typically printed or stamped on the baton or listed on the original packaging. If your baton is a different brand or a non-R variant in the TSB line, compatibility is not guaranteed and the end cap may not thread correctly.
Does adding this end cap affect how the baton handles?
At 0.2 lbs, the end cap adds negligible weight to the overall baton and doesn’t meaningfully change balance or swing characteristics. The threaded connection is flush with the baton profile, so it doesn’t create an awkward grip point or alter the baton’s collapse-and-extend function.
Does this end cap work on windshields?
Windshields are laminated — they’re designed to hold together on impact rather than shatter, which is what prevents glass from flying into the vehicle during a front collision. The end cap is intended for tempered side and rear windows, which shatter into small pieces on focused impact. For windshield escape, a seatbelt cutter is the more practical tool.
Can this be removed when not needed?
Yes. The threaded connection allows the end cap to be screwed on and off as needed. Some users leave it permanently installed; others remove it depending on carry context. Either approach works — the threading is durable enough for repeated installation and removal without degrading the fit.
