Dynasty Hardware AUG-03-26D Grade 2 Commercial Duty Classroom Function Keyed Lever Lockset ADA Satin Chrome Finish

The instructions recommended through bolts, but I did not use them as it's a low use lock. You can get a good squeeze on a steel door without them. The screws have serrations in them to prevent them from backing out, so if you detect grinding, it's probably just doing its job. Follow the instructions exactly, particulary on mounting the lock key lever. If you try to wing it, the lock won't work right. Rotate the lock clockwise 90 deg with one hand and insert the lever with the key with your other hand. Took me a couple times. The levers have some play in them, so not super high quality. It's a value lock at a value price. It won't beat the true pro brands in fit and finish, however.

Exactly as described. Super easy to install. A monkey could do it. Seems stronger than residential hardware.

Made in Korea. Comparing with Sargent locks we had, it is not bad at all. Almost same feeling, similar weight(little lighter), works great with only 1/3 price. Both private and passage works great. Highly recommend

Works pretty good for a security door. I like the way it will always stay locked or if you pop the button it unlocks.

I ordered this for my new exterior door on my home. Nice lockset. I have a commercial lockset on my garage but I didn't install it. I decided against it for my house as I thought it was too excessive plus the difficulty. If you need a super duty lockset and have experience with these kind of locks, I would get it. It looks like very good quality.
