The product is good but was missing parts
This shopper rated the product 5 out of 5 stars

I’m leaving a 5 star review because the product is good and as described and I don’t think simple error should result in potential business loss. The issue I had is that it arrived without the striker plate, when I called they sent out a new striker plate, but didnt send out tracking for the replacement part which left me in limbo wondering when it would arrive. Unfortunately it ended up being 3 weeks from point of order until I had everything I needed in order to install the handle. Which is frustrating when you’re waiting on “payment upon completion”

High Quality, Great Service
This shopper rated the product 5 out of 5 stars

Storm door knob in brass is just wonderful, perfect for our needs. High quality, heavy, and easy to put in. Ordering was seamless. Item came within a weeks time. Great company to order from.

Perfect!
This shopper rated the product 5 out of 5 stars

We needed a new lever to replace the broken one from our 55 year old wrought iron storm door. Very helpful customer service personnel helped with measuring (square 9/32" spindle, 20 threads per inch) and decide that the lever with this set would be a likely fit. Got it today (fast shipping too!!) and it was a perfect fit! Yeah!!!!! Thank you for great products and great customer service.

Beautiful hardware, but...
This shopper rated the product 3 out of 5 stars

I bought this because of its vintage look for our 1912 Craftsman home's screen door and while it looked beautiful, the knob just spins around freely and you have to push it hard to get the mechanism to turn. The funny thing is that I'm not the only one who's experienced this. A neighbor who bought the same product is having the same issues. Has anyone else had this same issue?

Perfect fit, work's the same as the old one from 35 years ago. Great fit and finish.
