C16-09322 HUOPO 10 Inch Gas Strut, 40Lb/178N Lift Support, c16-18233 Shocks for RV Cabinet Door Truck Pickup Toolbox Toy Box Storage Box, Set of 2

Great replacement for the failed hydraulic strut in my Sentry Pistol Safe. Took about 20 minutes to remove the old, failed hydraulic opener and put in the new one. The ends on the new and old struts are different. Just screw off the ends of both and put the Sentry strut ends on the new ones. Works like a charm. Lid opens fully and rapidly again. I put the second strut in the safe in case this one fails like the original did; it will be ready to change out again.

I needed to replace the original strut on my Sentry biometric gun safe and purchased this to do so. The quality of this product is good and the installation went well and was fairly easy. There are some decent videos on U Tube to help. Note, you need to save the original strut as it is necessary to remove the end pieces of the new unit and re-use the original pieces that the safe came with as the originals are the correct dimension whereas the new ones are not an exact fit, but this is not a problem as these parts are the correct threads and simply screw on and off. The safe is back to its original operation and again works well. Good product and fairly priced.

even easier than I expected to install and works super well. combined with fast shipping. don't know why I didn't get it sooner.

Good replacement for Sentry gun safe but did need modification. One end of the spring required the removal of the mounting head as its different from what is needed, took that from the old spring. the other end also had to be removed as it was hitting the side of the safe and would not open due to hitting the inside. Again removed mounting head from the old spring. Short story is that the mounting points/heads needed to be taken from the old spring and used to make it work. Works great once you got them installed.

These fit well and are stronger than original. I would purchase again. Very pleased.

Works good to replace the shock on the door of a cordless hole puncher storage device made by Sentry

These work perfectly easy install great product. I would recommend these to anyone.

This was perfect for replacing the failed hydraulic strut in our Sentry Pistol Safe. My husband opened up our safe to check the battery and noticed that it would no longer just "pop" open like it is supposed to. We removed the old, failed hydraulic opener and installed one of these it its place. You do have to unscrew the ends off of the Sentry strut and connect it to the new one so that it will connect correctly. After that, it worked like a charm!
