HUOPO 7.5 inch Gas Strut Sentry Safe Replacement Parts, 20Lb/89N Gas Shock Spring Lift Support for Truck Tool Box Lid, RV Cabinet Door, Compatible with Sentrysafe QAP1BE, C1615046, Set of 2 Pcs

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.

Very strong. Fit my Matco tool cart at work. Easy to i stall and worked as designed.

Perfect fit. Easy to install with easy to follow instructions

Worked perfectly for my camper shell door. Made well Very happy

Thes shocks them selfs are very good but the brackets are flimsy.east to install holds a lot of weight

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.

Perfect fit. I used on my boat and had them installed in minutes.

Recommended...very good!!
