SentrySafe Pistol Safe Strut Replacement

After a few years, your SentrySafe Pistol Safe may not open like it used to. You can easily replace the original strut with an inexpensive replacement gas strut, to resolve that issue.

Sentry Pistol Safe Strut Replacement

Like so many pistol safe owners, my SentrySafe pistol safe lid stopped springing open, after I unlocked it. 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. This is not the same gas strut, that originally came in the SentrySafe pistol safe, but it fits, and it works great.

These Apexstone 80N/18lb Gas Struts come in a 2 pack, for under $10 USD, from Amazon, so you have a spare strut, for later on. All gas struts will eventually fail, over time,  so it’s nice to know that you will have a spare strut for the next time.

The Apexstone 80N/18lb Gas Strut specifications:

  • Length (Center-to-Center): 7 inch (180 mm)
  • Compressed Length (Center-to-Center): 5.12 inch (130mm)
  • Force: 18 Lbs (Per Strut)

Replacing the Gas Strut on your Sentry Safe

You will need some simple tools:

Make sure to put something in the safe, to keep the lid from falling and locking shut, while performing this procedure.

To remove the original strut, use a phillips screwdriver to unscrew the screw on the bottom of the strut, and use the wrench and socket to remove the connection at the top side of the strut.

Once the original strut is removed, the connectors, on the top and bottom of the strut, can be unscrewed and moved over to the new gas strut. The new gas strut has threaded fittings, on both ends, that also unscrew.

Keep in mind, once you install this strut, your lid will not open quite as far as it used to, but it will still open about 85%, well enough to retrieve your belongings from inside the Sentry Pistol Safe.

After a couple years, your Sentry Safe Pistol safe may not be springing open, after you unlock it, this should help you resolve the issue, or to prepare for this, when it does finally happen.

  1. Thanks!, life saver.

  2. Ordered (2) of these for our safes. FANTASTIC!!! Quick to assemble and saved about$45.00.
    Great job. Thanks Much !!!

    • I was in the same boat. Glad this helped!

      • Holy crap…I had called SentrySafe for new struts thanks to a failure, of course. Customer service said, “they’re back-ordered so call back in 6-8 weeks.” They’re dead to me. I ran across this in my frustrations and am so glad I did. Worked like a champ and took 15 minutes to install 2! Thank you!
