Review on Premium Replacement Keyed Patio Sliding Door Handle With Mortise Lock And Key Cylinder, Fits Doors 1.5 To 1.75 Inches Thick, Reversible Non-Handed Design, 3.94-Inch Screw Hole Spacing by Daniel Taylor

This handle/lock set fit my door well. I didn’t even have to change out the latch part. Once installed, it worked smoothly and has a sturdy feel to it. The installation does require some cutting of the flat, metal pieces that engage with the latch assembly. They are too long, likely to accommodate thicker doors so I’m sure it will need to be cut regardless of the type of door you have. I put the lever on one side and the lock set on the outside as they would be installed. Then I marked them both where they intersected in the middle. The idea is to cut them so they both engage the latch assembly. Cut them too short and one or both will not engage the latch assembly. Cut them too long and they will either not fully tighten down or will bind (or both) as they butt up against each other in the center.Once marked, I put them in a vice and cut with a dremel tool (as others have mentioned). If no dremel, a pair of clamping pliers and a hack saw will work too. It will be more of a challenge hold them while cutting though. Once cut to length, the rest is pretty simple. You may want to file off the burrs after cutting.It works great once installed. Key is smooth as is the latch engagement.I have been using it for a couple weeks now and no issues. I will update if anything changes.
