Fitting Shelves

 

The Adjustable Slotted Shelving Systems consist of varying lengths of steel or aluminium and specially designed brackets, which fit into the slots.  The brackets also come in varying lengths to accommodate different widths of shelving.  This system is ideal for anyone who requires flexibility, as they can be fitted to any height, into any space, with many configuration options and are fully adjustable even after installation.
The slotted lengths are fitted to the wall vertically with the distance set between them governed by the space they fit into and the material used for the shelves, as well as what they are expected to carry.
Because they are fitted to the wall, the weight that they will carry is dependant on the wall fixing, different to floor standing units.

Fitting

To begin with, you must consider how many vertical uprights you will require, which in turn represents the number of brackets.  As mentioned earlier, the type of shelf you intend using and the distance that the brackets are set apart, is governed by the weight you intend putting on them.  As a guide, for light or normal use, I would suggest that the brackets be no more than 600 mm apart if using Veneered chipboard.
The next consideration is the overall length of the shelf that you intend using and the overhang at each end.  Manufactures recommend that the shelf should not over hang the side of the bracket by more than 1/6th the width of the shelf.  Based on this, a 600 mm shelf would have an overhang of 100 mm.  I suggest between 100 mm to 200 mm as a minimum and maximum for the overhang. 
The uprights come in a variety of lengths, depending on the manufacturer.  One suppliers that I checked, supplied two lengths 950 mm and 1400 mm.  Another had two ranges with sizes from 430 mm, up to 1980 mm in one and from 500 mm to 2000 mm in the other.
In this example, I am using veneered chipboard shelves each at 1000 mm in length. The overhang at each end will be 100 mm and three uprights at 950mm in lengths will be used, set 400 mm apart. The height is set so that the top is within easy reach of 2000 mm.
Using a pencil, place a mark on the wall where the centre of your shelves will be, (2000 mm from the floor). With the upright held in position up to this mark, use a bradawl to mark the wall through the top screw hole. Remove the upright, drill a hole at this point and insert the wall plug.  Reposition the slotted section back over the plug and insert the screw but do not fully tighten. This allows the upright section to be free to swing to the vertical position.  By placing a spirit level up against it, you can make any fine adjust that may be necessary until plumb. With the upright in the correct position, mark the wall through the bottom screw hole and fix in place. Now it's just a matter of marking the wall through the other screws holes and installing the remainder of screw.
With the first upright in place, the position of the second can be established. To do this, measure from the centre of the fixed upright, again from the top and place a small vertical mark on the wall, 400 mm to its right. This is the centre line for the second upright.  Using a spirit level, level across from the top of the fixed upright, so that the small vertical mark is crossed. This now gives you the top horizontal position of your second upright.  Using the same procedure, fix the second upright in its position, again so that it can be adjusted after fitting the top screw. The next step is to adjust the second upright so that it is parallel to the first. The bottom screw can now be fitted followed by the remainder of the screws, completing the installation of the second upright.
The third and final upright can now be installed by following the same procedure.
With the three uprights in position the shelf brackets can be slotted in position ready to receive the shelf.
Depending on the type of system, the way that the shelf is fixed onto the bracket from the underside may differ.  The heavier gauge systems are screwed in position, where the lighter gauge may only use small pins. Though this at first may seem inadequate, it should be remembered that the pins only serve to prevent the shelves from moving, or being pushed from their position and does not contribute towards it overall strength.
