Details
The HC-150 Stacking Clip is a thin, strong, steel clip for joining 1-1/8" plywood panels to 1-1/2" lumber. It's an inexpensive way to add inches to your forms. Just slip one clip over the top of each form panel, then slide a length of "2 by" onto the top. Nail holes provided to secure the clip to plywood and board. Strips easily.
Stacking Clips are a great way to maximize an investment in 8 ft panels, providing a quick and inexpensive way to pour up to 8 ft 11 in walls without investing in new wall panels.
When used on the top of 6-bar forms (or other forms where the top panel bar is within 8 inches of the top), generally only the top of the planks will have to be tied together. On 4-bar forms, Steel Dog Stacking Spreaders are a fast way to prevent both the top and bottom of the planks from spreading.
Other Uses
Stacking Clips can be used to make temporary filler panels on the spot from 1-1/2” lumber (or use HC-112’s and 1-1/8” plywood.) As shown on the right, joining up to an existing wall sometimes requires a scribed board to match an uneven surface. Use HC’s to join a 2x4 or 2x6 to the first form panels. Cut board to match adjoining surface. Secure ties at joint between first form panel and the temporary filler with ST-100 Half Clips.
Use the same technique to make panel-to-panel fillers in the middle of a wall to get exactly the width you want, or to cut for wall pass-throughs.
