3M™ Dual Lock™ Reclosable Fasteners are used to attach vinyl protective trim to the top edge of the end panels of refrigerated cases that are used in the deli section of grocery stores.
Dual Lock Fastener SJ3551 is attached to the back side of the vinyl trim. Dual Lock Fastener SJ3441 is attached to the barrier compound that run along the top edge of the stainless steel or fiberglass end panes. The compound is used as a part of the foaming process to create a thermally insulated panel. The two parts are mated together with light finger pressure. This approach allows no-tool removal for any required repairs.
Improved Appearance - fastener is hidden from view, providing a clean, uncluttered look, no screw holes or screw heads to cover.
Fast and Easy to Use - No drill holes needed. After removing adhesive strip and adhering fastener to protective trim piece and end panel, simply slide the trim piece into position and "snap" into place.
Reclosable - long lasting reclosability provides easy removal or replacement of trim pieces.
