Nuk3y 9000 Series Grade 1 Door Closer

I installed this closer on a fire-rated, weather-stripped, metal door that did not have a closer. This door exited out from my house into the garage. I needed a closer with an option for a parallel arm mount. Several “top ten” website rated this one highly, and its price on Amazon was lower than expected.The “user manual” is just diagrams with specs, one page for each of the three installation options (regular arm, top jamb, and parallel arm). Fortunately, I found several videos on-line for closers similar to this one. Be advised that the “installation manual” for this product is just the templates.Since I had never installed a closer before, I would have appreciated some step-by-step instructions. But as I proceeded to install the closer, I realized it was lot easier than I thought. For me, the templates were great, and saved me a lot of time figuring out the spec sheets. All the necessary parts were included, along with many extra parts. Now that I have installed one of these, I am quite confident I could do it again without any instructions.The closer operates at one speed until it reaches the set backcheck angle, and then goes faster to make a secure close. I fiddled with the latching and speed regulation valves for about 20 minutes until I got the door to close securely every time, despite the weatherstripping. I expected I would have to increase the backcheck angle but that proved to be unnecessary. My compliments go to the factory for their initial settings. For now, I am leaving off the plastic cover in case I need to make some more adjustments after the closer settles in.I am very pleased with this closer, and I would buy it again.Update: The closer has been installed for a week, and showing no sign of needing recalibration. So I have put on the cover for a nice look. In the parallel mount position, the screws holding the cover are at the top. I decided to just use a few toothpick points instead of the provided screws in case I want to make adjustments later. Still working great.

With working from home, I was getting tired of constantly hearing the door to the garage slam and the house shake. I had looked for a number of different options to prevent slamming, but in the end the traditional door closer was the best solution.
Hardware wise this door closer is well made and comes with everything you need for several different installation options. The instruction manual on the other hand seemed like it was written for a different model. As this was my first time installing a door closer I wanted to take my time, follow the instructions, and make sure I installed it right the first time. What threw me off is the instructions show a different forearm (one with a lock nut instead of a screw,) a different arm screw, and a pinion cap (which is not included, but the optional plastic cover is.) Additionally the number of full 360 turns required to make adjustments on the sprint power setting were different than what was in the manual. I installed the closer on a 30" wide door so I needed to use size 1. The spring power screw stopped just before 9 full turns, not the 10 and printed in the instructions.
As far as mounting, included are three templates for the three different install options (regular, top jamb, and parallel) and each template is double sided for either left or right hand installation. The templates were spot on. I drilled my pilot holes through the template and all the screws lined up perfectly. The included self drilling screws worked perfectly and easily. Additional hardware is included for mounting into a metal door as well.
When I first installed it the sweep and latch adjustments were completed closed, so the door didn't close at all. Opening them up too much the door slammed shut. It took some minor adjustments to tune it just right. While it's no longer possible to slam the door and no longer possible to leave the door open, the downside is will small children the door now requires a lot more force to open which is not so easy for my kids.

The media could not be loaded.  Needed automatic closet for a bookshelf door with a mag-lock latch. This performed exactly as needed, even considering the off spec install on the thicker door. It needed a slight adjustment to the close strength because door thickness caused it to be a finger trap.The instructions were extremely detailed and well written. Included in the kit were templates and instructions for three different install methods based on your style of door ie. in-swing/out-swing and also provisions to meet ADA requirements based on wheelchair access.Solid product that did everything I needed out of it.
