Clear opening (the area required for the slide out shelf to slide through) is measured typically in three different ways, depending on your cabinet style and hinge placement.

Opening (a) is typical for a middle cabinet installation and will not have door hinge interference. Measure this distance from frame to frame on a face frame cabinet, and from inside wall to inside wall on frameless cabinets (open door and check if any part of the door edge protrudes into the opening, subtract this amount if it does)

Opening (b) is a base mount and because of the hinge protruding into the opening, the clear opening is measured from the edge of the hinge to the other side

Opening ( c ) is a base mount and has two hinges protruding into the opening, in this case the measurement is from hinge to opposite hinge.

Variance: if the hinges do not protrude more than 1/2” and are 2 3/4” or more above the cabinet floor, then they do not become a factor and the measurement would be clear opening (a)

All pull out shelves are custom made in 1/8” widths, if you are in doubt always round down

Our Shelves come with standard drawer slides which are 3/4 extension slides, there are several mounting methods and hardware that make installing easier that are optional and explained below

Measuring Depth: Measurement should be from cabinet back wall to cabinet front minus 1”, Typical base cabinets will be 23-23 1/2” deep, in this case, we recommend ordering a 22” deep shelf

Mounting Definitions

SIDE MOUNT: Drawer slides are mounted directly to the cabinet wall in frameless cabinets or to either spacers or built out walls to match the cabinet reveal on framed cabinets ( cabinet reveal is the distance from the inside cabinet wall to the edge of the clear opening. This is typically 3/4”-1”

Base Mount : Drawer slides are mounted directly to either the base of the cabinet or to a full depth shelf with the use of Zinc L brackets. When this option is chosen at time of ordering, we will attach the drawer slides to the L brackets and will arrive ready to install with screws provided

Half Shelf Mount : Drawer slides are mounted onto the cabinets half shelf and into the face frame in the front. When thisoption is chosen at time of ordering, we will attach the drawer slides to the L brackets in the rear of the slide and will arrive ready to install with screws provided

Rear Socket Mount: Drawer slides are mounted to the back of the cabinet and to the face frame in front. When thisoption is chosen at time of ordering, we will attach the drawer slides to the rear sockets and will arrive ready to install with screws provided. Rear socket have a 2” adjustment allowance, so a 22” deep shelf with rear sockets can be mounted inside of a cabinet up to 24” deep

Other

Drawer Slide Sizes: Drawer slides are in even increments so if a 19” deep shelf is ordered then it will come with a 18” drawer slide, 21 with a 20” slide etc.

3/4 Extension Slides that come standard with our birch pull out shelves extend the drawer 3/4 out ( a 22” slide will extend the drawer 16”) and are only available up to 22”, so if a 26” deep drawer is ordered with 3/4 extension slides, the slides will be 22” long maximum

Full Extension Slides extend the drawer fully out the length of the slide. Full extension slides are available up to 26” deep

Full Extension with Soft Close is a full extension slide with a gas cylinder that softly closes the drawer itself in the last 1” of inward travel. These slides have to be installed properly or will not work as intended. If the slide is too tight it will not retract properly. Nice slide, but for confident installers

Rear Sockets, 3/4 extension rear sockets are a plastic nylon and subject to stress fractures, Full extension rear sockets are a zinc alloy and not subject to stress fractures
