PLEASE READ CAREFULLY AS STOCK HAS CHANGED AGAIN.
The Screw On as explained below are now Sold Out for one side.  We have found a number of Clip On for the other side.  Everything on the brackets are the same as far as fitting your drawer slide, the only difference is one side will be a Clip On, the other will be a Screw On. 

These are a replacement for the Alfit / Mepla drawer slides.  The items you came here from are discontinued by the manufacturer.  You get 1 Left and 1 Right. These are from the same manufacturer BUT these are not "Clip On" as the others are.  These you "Slide On" and tighten the screw on the side.  The smaller screw that is set back is for the up and down adjustment.  These also have plastic dowels that you will need to remove simply by removing the screw and discarding.  Use your old wood screw to attach this bracket on your drawer front. 

Please see link below to be sure you are getting the correct item as there is No Returns on these.
