Our Grid Panel systems are ideal or utilizing overlooked wall space in retail stores. To be most effective, a row of panels may be attached using Our Butterfly Joining Clip for Grid Panels. The clip is used to connect two (2) grid panels together. We know that it is the most cost-effective connector available on the market. Works perfectly when connecting panels together in the middle of a panel as with grid bases BLK/4BA and BLK/G48. The clip may be color-coordinated with your Grid Panel system to disappear yet provide excellent support. That means our semi-gloss black epoxy finish clips will match our semi-gloss black epoxy-finish Grid Panels, etc. This is not an item found at a big box retailer or your local hardware store, but has been specifically designed to provide a more secure hold for two conjoined panels.
