DUAL BIT CLIP FITS ALL DeWALT 20 VOLT TOOLS (DRILLS, HAMMER DRILLS, IMPACT DRIVERS), THAT HAVE A MOUNTING SLOT FOR EITHER A BIT CLIP OR BELT HOOK.

***BITS DO NOT SNAP INTO HOLDER FROM THE TOP, YOU SLIDE THEM IN OR OUT OF THE HOLDER FROM THE FRONT. DESIGNED FOR BITS 2" AND LONGER.....ALSO THE BITS SHOWN IN PICTURE  ARE NOT  INCLUDED

This is a non oem part but fits and performs very well on either side of the tool.  I have tested it on basically the whole line of 20 volt tools with all battery combinations.   (over 500 sold in the past 90 days)

Your clip will come with two screws of different lengths, use whichever works best on your tool, making sure that the screw does not penetrate too deeply into the tool or you may not be able to slide in the battery.  You may wish to use the longer screw first to draw everything into place, then, if found to be too long, remove it and use the shorter screw as your permanent fastener.  

HINT: IF YOU DON'T USE A BELT CLIP WHY NOT INSTALL ONE OF THESE ON EACH SIDE OF YOUR TOOL.  CARRY 4 BITS TOTAL ALL ATTACHED TO YOUR TOOL.

I think these will be a great accessory to add to your tool.  Give them a try!  Not satisfied for any reason simply send it back in an envelope for a full refund.
