Martin Yale Master® DP20 Duo™ 2-Hole & 3-Hole Punch

Item #: 04MYDP20

The Martin Yale Master® DP20 Duo™ 2-hole & 3-hole punch is a unique office paper puncher that allows for perfect centering and punching for both standard 3-hole letter size pages, and 2-hole top punched pages. This dual punching allows for more versatility and makes it a great choice for any office environment, including legal and court reporting offices and more. Changing from three to two hole punching is very easy as there are no screws or adjustments needed -- instead, one side of the punch is dedicated to 3-hole and the other side is dedicated to 2-hole, so just place your pages on the other side. This patented design is a unique feature that lets you accomplish two different punch patterns with one, compact unit. Both sides can punch through up to 20 sheets* at a time, creating very slightly over-sized round holes measuring 9/32" to allow for easy page turning. The three hole side features standard US three hole spacing of 4 ¼" (center to center) while the two hole side features standard hole spacing of  2 ¾" (center to center). A large full size chip tray doubles as a non-stick bottom that holds the punch steady to your workstation, and pulls off easily for wast emptying. The handle locks into the down position for easy storage when not in use. Add versatility to your office when you buy the heavy duty Martin Yale Master® DP20 Duo™ hole puncher online.
