3M’s Hookit II attachment system, is
the ultimate in re-usable attachment
systems. Hookit II discs turn the
Hook & Loop system upside down
by reversing the hooks and the
loops. In the Hookit II system the
patented stems (hooks) are placed
on the back of the disc, while the
loops are placed on the back up pad.
Research shows that the hooks on
traditional hook and loop back up pads
are prone to wearing out prematurely,
that’s why we placed the loops on the back
of the disc instead of the pad. The advantages
of the Hookit II system are as follows:
• Patented stems (hooks) are uniformly placed over
the face of the disc for finer, more uniform finishes
• The film backing of the stems on the back of the disc
provides for greater tear resistance, increased
durability and improved flexibility of the coated
abrasive disc
• The loops on the back up pad provide for improved
heat dispersal, more secure attachment, and up to
four times the life of a conventional hook and loop
back up pad
• Available in 3 1/2", 5", 6", 8", 12, and others.

abrasives
3M offers a complete line of traditional hook & loop
style discs for areas where adhesive backed discs may
become contaminated by dust, dirt, or flying debris.
• Hookit attachment system allows for re-attachment
of the disc between grade shifts or work pieces
• Hookit backing does not become contaminated by
dust, dirt, and debris for maximum utilization of
abrasive dollars
• Available in 31/2", 5", 6", 8", and others
