In most cases you won’t need any screwdrivers, sockets or wrenches to replace the strut. I’d recommend some fresh Duracell AA batteries. Also do yourself a favor and change the batteries, while you are doing this procedure. Make sure to put something in the safe, to keep the lid from falling and locking shut, while performing this procedure. Replacing the Gas Strut on your Sentry Safe If you are in a rush to replace the spring, you may be able to find a fit in this spring assortment pack. Please stand by, while I test and review the springs, for fit and function.

I will update when I have one that works correctly. I am testing some aftermarket springs also, to give the lid a bit more boost.

End Fitting: Ball Socket U Band (Nylon)=10mm=3/8″=.39″.The BOXI 4053 Universal Lift Support Struts specifications: If you want your SentrySafe to open further, and are fine with spending a bit more money ($22ish) on this project, the BOXI 4053 Universal Lift Support Struts (pack of 2) will open to to a length of 7.50 Inches, and with a force of 25lbs.

You can go inexpensive with the Apexstone 80N/18lb Gas Struts for around $10, or you can spend a bit more on the BOXI 4053 Universal Lift Support Struts ($22ish). This is not the same gas strut, that originally came in the SentrySafe pistol safe, but it fits, and it works great. After months of searches, I was able to locate a compatible gas strut, that fits in the Sentrysafe Pistol Safe, including both the standard version and the biometric model. Like so many pistol safe owners, my SentrySafe pistol safe lid stopped springing open, after I unlocked it. You can easily replace the original strut with an inexpensive replacement gas strut, to resolve that issue. After a few years, your SentrySafe Pistol Safe may not open like it used to.
