NSI SL3™ Hook & Loop Backers

All the NSI Hook & Loop backers are designed to lock into the red SL3 adapter.  They're constructed with high quality hook & loop and superior adhesives for long lasting durability.  All required machining is accomplished in house and they are hand assemble and trimmed to our high standards.  Each backer has a specific purpose and many were developed in conjunction with stone fabrication and restoration experts. Also called backup pads, backing pads and backup heads.

3″ FOAM Padded hook & loop backer (3.0″ actual diameter):

• A semi-soft foam rubber pad allows this backer to conform to contours.
• When combined with a 4" resin pad (a well worn pad works best), this will be your best Ogee polisher and conforms to a tight inside corner radius just as well.
• 3/8″ of semi-soft foam padding under the “hook” to allow flex into contours.

3″ RIGID Plastic hook & loop backer (3.0″ actual diameter):

• We use this to drive the small center portion of the natural blend tan fiber pad or cut down resin pads in restricted areas.
• Can be used with 3″ turbos, 3" resin pads, or small fiber pads
• This is the 3″ backer we provide in our top polish kit.

4″ Flexible hook & loop backer (3.6″ actual diameter to fit 4″ resin abrasives):

• When combined with a 4" resin pad (a well worn pad works best) this is the perfect attachment to polish inside radius corners and inside curved sink cutouts.
• Intended for use with a flexible 4″ resin pad to polish smooth inside curves
• Perfect for polishing inside curves on sink cutouts

4″ RIGID Plastic hook & loop backer (3.8″ actual diameter to fit 4″ resin abrasive):

• Locks into the SL3^® Snail Lock Adapter
