I bought a pair of springs to hold open the doors of two small cabinets (one spring per cabinet) that are installed horizontally in the soffit area above existing wall cabinets in the laundry room. The installation instructions that came with the spring are not very useful or complete. The doors and the cabinets are about 9-in high, so I chose the Apexstone 80N/18lb 7-in long springs for the application so that the spring physically fits within the cabinet. The small lower end of the piston of the spring is pinned to the wall of the cabinet near the bottom front and the cabinet and the upper larger cylinder end attaches to door near the hinge. It took a bit of trial-and-error to get the proper location of the upper pin on the door. In the hope of saving others some grief, let me outline the logic and the process I used for finalizing the critical location of this door pin: 1. The spring (cylinder) is installed when the door is open (hinged horizontally at the top of the cabinet in my case) and the spring is fully extended and holds the door open horizontal at about 90 Deg. 2. When the door is closed by pushing it down and rotating it, the weigh of the door and the hand force compress the gas spring and gently close the door in a vertical position. 3. In the closed position the door is kept closed due to the action (moment) of its weight which is stronger than the spring action (moment) around the hinge. The spring has very little resistance in this position. 4. The key objective in selecting a proper position of the door pin is to balance the action (moment) of the spring with the action (moment) of the weight around the door hinge. It is like balancing two riders around the pivot of a teeter-tooter swing. One rider represents the weight of the door and the other simulates the spring force. The pivot is like the door hinge. The two actions would be in balance when the products of the weight (force) times the distance of each rider from the pivot are exactly equal. 5. Applying this balance requirement to my situation, the product of the weight of the door (Wd) times 1/2 of its height (Hd) or the distance to the hinge should balance or be equal to the product of the spring force (Fs) when fully extended times the critical distance (Sd) of the upper spring end from the hinge. This means the product Wd X (Hd/2) must equal the product Fs X Sd. If three of these quantities are known, one can solve for the fourth. That is exactly the case in my situation: the manufacturer lists the spring force Fs as 18lb, one 1/2 of the door height (Hd/2) is 4.50-in, and the weight of the door Wd is 4 lb. So knowing the three quantities I can determine the fourth, the critical distance Sd required for balancing the spring and the door actions. The distance Sd is Wd X (Hd/2)/Fs. Computing Sd = 4 lb X 4.5 /18 lb = 1 in. 6. So the spring pin should be located on the door (the critical distance Sd) about 1 inch from the hinge. 7. I pinned the piston (bottom) end of the spring inside the cabinet at the lower right front corner and attached the upper cylinder end on the door at about 1-in from the hinge. The bracket that accepts this upper end of the spring has long slots for adjusting the critical distance. 8. It turns out, I had to increase the critical distance to about 1.25 in to allow for the damper action in the cabinet hinges. 9. I hope the attached pictures will help clarify the verbiage of this long-winded write-up. 10. One last comment: to separate the cylinder spring from its pivots, you need to insert a little screwdriver below the chrome split ring in one of the two locations provided while pulling out to pop the socket out from ball joint at either pivot. The springs work great, almost magically. They prevent the door from closing inadvertently on the fingers. desertcart fulfillment is always top notch. Little tricky to install, but you will be greatly rewarded if you are patient and do not give up. Review: Sentry Pistol Safe gas strut replacement - The gas strut on my Sentry Pistol Safe stopped working after about 4.5 years. I read the desertcart reviews for the Apexstone 80N/18lb Gas Strut and decided to give it a try. Everything I read was accurate and the Apexstone product is an almost perfect replacement... and works great!! The only difference between the Apexstone and the gas strut that came with the safe is the lid lift height which is an insignificant an inch or so less. This is not a problem at all... the lid still lifts well and high, allowing more than ample access to the contents of the pistol safe. Installation is a breeze if you have the following tools: a medium Phillips head screwdriver, an 8 mm metric box or open end wrench; and a 13 mm metric box of open end wrench. Simply unscrew and remove the fittings and spring from the old gas strut, unscrew and remove the fittings from the Apexstone strut and replace them with the fittings that you removed from the original strut. Install the Apexstone strut (and don't forget the spring) and the job is done. With the proper tools you should be able to complete the removal and re-installation in 5 or 10 minutes. It is as quick and easy as that. This Apexstone 80N/18lb Gas Strut fits great, works great and costs a lot less than a replacement gas strut from Sentry. If the gas strut on your Sentry Pistol Safe is getting a little "tired" it is time to replaced it and the Apexstone 80N/18lb Gas Strut is perfect and solves your problems. The purchase includes two gas struts so you have an extra to keep handy for the next time you need a replacement. Gas struts don't last forever. This is a great product and the perfect solution for Sentry Pistol Safe owners. I recommend it highly, and you can't beat the price. ## Features - If you are buying to replace the gas strut on the gun safe, please be sure to first confirm that the center-to-center measurement of the original gas strut is around 7 inches.
