4-Post L&T Shelving

Mobile Systems Specifications

Introduction

The shelving is a four post style design consisting of three basic components:  Uprights, Shelves and Shelf Supports.  No clamps or special tools are required for assembly.  There are no sway braces, gussets, nuts or bolts to slow assembly, or detract from form or function.  The shelving has a clean appearance without holes on exposed surfaces except where the shelves, back stops and center stops are slotted or punched for file dividers, and the shelf center is punched for center stops.  The front and back flanges of the shelf are flush with the outside face of the post.  Shelves are adjustable on 1-1/2" centers.

Material and Workmanship

The shelving is made from only the finest materials and highest quality workmanship.  The sheet metal is commercial quality steel fully pickled or equivalent.

SPECIFICATIONS OF SHELVING COMPONENTS

Open Uprights

1.0 Open uprights consist of 18 gauge cold rolled steel posts rolled into a 2" wide hollow "T" or 1" wide hollow "L" shape with keyslot holes punched on 1-1/2" centers, along the inner wall only.  There are no holes on the face of the post.  The front and back posts are joined by welding 18 gauge spacers to maintain the required distance apart and add rigidity to the assembly.  Center spacers are 3" high flat strips.  Top and bottom spacers have an 11/16" stiffening flange with two 1/4" holes to allow mounting to floor or mobile bases.  All uprights 64" or less have three spacers.  Uprights 76" to 88" high that are less than 30" deep have three spacers.  All other uprights have four spacers.  The "T" uprights are used as common intermediate uprights and "L" uprights are used for row ends.

Closed Uprights

2.0 Closed uprights have the same specifications as open uprights, except the 18 gauge spacers are replaced by welding 24 gauge closure sheet with a special offset stiffener flange at the bottom of the closure sheet.  The flange has two 1/4" holes to allow securing it to the floor or mobile base.

Shelf

3.0       Shelves are formed of 22 gauge cold rolled steel with 25/32" high channel formation on all sides.  The return flange is formed to 120 degrees permitting easier installation.  Slotted shelves have shelf divider slots on 2" centers.  Outermost slots on thin shelves coincide with the inner edge of the post so a file divider can be used to prevent files from leaning into the upright.  Shelves 18" or deeper are punched for center stops.

Shelf Supports

4.0       Shelf supports are formed of 14 gauge (also available in 11 gauge) hot roll pickled steel, 11/16" high with flat ears at either end.  Semi-tubular rivets with a 7/16" diameter head is staked onto ears.  Shelf supports for heavy and x-ray shelving are the same as above, except they are 1-1/8" high.  Supports are available with single or double rivets.  The bottom of single rivet heavy supports can fit flush with the floor, and single rivet thin supports are optional on intermediate levels.

Back Stops

5.0       Back stops are formed of 18 gauge steel with a 7/16" channel formation at the top and a 7/16" stiffener flange at the bottom.  Its face is slotted on the same centers as the shelf to receive and retain file divider tabs.  Ends have one shoulder rivet with a 7/16" diameter head.  Rivets are set in keyholes on the inner wall of the back uprights posts.  Back stops also act as a stop for files, and are used on single entry only.

Center Stop

6.0       Center stops are formed of 18 gauge cold rolled steel.  They are 3" high with mounting holes on 9/16" bottom flange, and a 9/16" box channel at the top which acts as a back stop with equal filing depth from both directions.  The face is slotted to retain file dividers on the same centers as the shelves.  Center stops are attached to the center of double entry shelves with plastic plugs or bolts and nuts.  X-ray center stops are the same as above, except overall height is 7".

Letter File Divider

7.0       File dividers are stamped from 20 gauge steel with two embossed tabs to enter matching slots in shelf and a retaining tab on the back edge to locate and stabilize divider against back stop or center stop.  Dividers are self locking on the shelf and are available in depths of 8" or 11", and are 8" high.

Backs

8.0       Backs are formed from 24 gauge cold rolled steel and are held in place by their reverse flanges on each side.  The side edges are formed in two reverse 90 degree bends to provide flanges 3/8" and 5/16" wide.  The flanges fit around the post and hold the back in place by retaining the flanges between the shelf support, the notch in the shelf and the post.  The top and the bottom of the back have stiffeners for additional strength.  Backs of 88" high or less are of one piece construction, while backs over 88" high are of two piece construction, connected with a back splice.

Sliding Reference Shelf (if requested)

9.0 Reference shelves are formed of 18 gauge steel and are attached to the underside of shelf supports, where needed.  A shelf extends 9" from the face of the shelf.  Reference shelves operate on ball bearing extension slides and can be mounted alone on single face units or, back to back on double face units.

Shelf Reinforcement

10.0 Reinforcements are formed of 13 gauge hot rolled pickled steel.  Heavy shelf reinforcements are 13/64" high with two 29/64" deep slots to fit over the short leg of a heavy shelf support.  Thin shelf reinforcements are 39/64" high with two pair of 23/64" deep slots.  The inner and outer slots fit over the short leg of the double and single shelf support, respectively.

Finish

11.0 All steel parts are thoroughly cleaned in a multi-stage washer.  An integral part of this stage is the application of a phosphate coating.  This results in superior paint adhesion and rust resistance.  The finest grade of industrial enamel is applied with electrostatic spraying equipment.  This insures complete and even coverage.  Coverage is capable of withstanding a minimum of 250 hour salt spray test per (ASTM) method number B-117 in a salt spray chamber as well as all normal resistance of a quality finish.
