Great Quality and Fast Weekend Shipping

I usually order wholesale parts when I need them, but this Prime-Line J 4516 Aluminum Diecast Flush Mount Extension Bolt was just as good in quality and arrived much faster when ordered on the weekend. The build is sturdy, and it functions just as expected.If you need a reliable extension bolt and don’t want to wait for a bulk order, this is a great option. I’d definitely order again when in a pinch.

Works perfectly to replace the old one in a commercial door.

Perfect replacement. Easy install. The hardest part of this entire process was figuring out this part was called a "flush bolt".
