This video is to bring you a closer look at the Bommer LB4310-350-652 3.5x3.5in Single Acting Spring Hinge-Full Mortise-Satin Chrome Plated. The swag on the hinge tells us this is a single acting full-mortise hinge. Single acting meaning that the door can only swing in one direction. Used commonly on 1-3/8" thick doors. Standard template pattern for the screw holes. There is a link below this video to the template that shows everything important dimensionally about this item. The 'LB4310' means that this a standard template pattern with a 96 thousandths of an inch leaf thickness. The 350 means this is 3-1/2" tall and 3-1/2" wide. The 652 means this is a steel based hinge in a satin chrome finish. There is a guide below this video in terms of door weight and size, this helps you figure out how many hinges you'll need. This is for 3070 doors only. For doors up 85LBS it's recommended you use two hinges, anything heavier use three. These hinges will mix & match with other standard 3-1/2" x 3-1/2" hinges, because the vertical axis of pivoting. There is better control over a door with the more hinges you use. With more hinges (meaning three instead of two or two instead of one) it seems there is better potential for the door closing and latching as well. This is non-handed, this will work with left or right handed applications. There is a link below this video to the instructions. Your tension collar is inside the top of the hinge, the tension rod is included. You'll insert the tension rod into one of the holes on the collar, rotate it clockwise, you'll reveal additional holes. Into one of those new holes you'll drop a tension pin (all you need is one per spring hinge). Available in several finishes on the website. This is maintenance free with lube bearing on the inside of the hinge knuckle. The mortising for the item is no different than any other hinge. This unit has squared off corners. These will include all wood screws and machine screws in a complimentary finish. There are also instructions on the back of the box. This Bommer hinge is made in the U.S.A.
