White Cardboard Corner Protectors
We sell a wide assortment of traditional cardboard corners for all types of frames. Our corners  
fold and have a locking tab which goes over the front lip so you don't need to staple or tape them
on the frames in most cases. All of our cardboard corners are made in the USA of 200# test
corrugated. They have a bright white finish and come on sheets with most scrap removed. They
are available in a variety of sizes and selling units for almost any situation - whether you're an
artist with just a few frames to protect, a frame shop or a large manufacturer. We stock these
corners in Chicago and Salt Lake City for fast delivery whatever your location. Just choose the
one you're interested in and click for pricing and quantities available.

THREE SPECIFIC REASONS TO BUY CARDBOARD CORNERS FROM US:
  • Our corners are scored not perfed - this means that all the folds are smooth and clean
    without the "dotted line" perforations that look so tacky.
  • Most of our cardboard corners are adjustable  This means they can be folded in two or
    three different widths so they're much more versatile than single-fold corners which will
    cost you the same or more from other vendors.
  • We offer quantity discounts for multi-box orders and you can mix and match corners on
    larger orders for the best combined pricing. We will automatically give you the multi-box
    price on larger orders or you can call for a specific quote before ordering.
