2 x 10 planks secured to the top of a wall of standard 8 foot, 4-bar panels. (For easier stripping, we recommend placing the HC's in the middle of each panel.) The tops of the planks still need to be tied together, either with strapping, banding, or Steel Dog® Stacking Spreaders.    

Using HC-150 Stacking Clips to Increase Wall Height

This foundation in Massachusetts had about 450 running feet of 8' 8" high wall. The contractor used Steel Dog® HC-150 Stacking Clips to secure 2 x 10 planks to the top of his existing 8 foot, 4-bar panels to do this pour at very low cost.

Because of the additional load that this height extension places on the top of the form panels (and, in turn, the top row of ties), we normally recommend using Stacking Clips on 6-bar panels, or any panels where the top row of ties is within a foot of the top of the forms. With special care, however, it is possible to use them very successfully on 4-bar or 5-bar panels, as shown here.

If you are in an area where there is a mixture of standard (<8 ft) and extra-height (between 8 and 9 ft) foundations being poured, you are faced with the dilemma of:

1) Switching to higher panels and struggling with finishing lower walls well below the tops of the panels,
2) Maintaining an inventory of both 8 ft and higher panels, or
3) Not bidding on higher walls.

With Steel Dog® HC-150 Stacking Clips, you have a fourth choice: keep your 8 ft panels and add the extra height when you need it.

  Another section of the same foundation wall after stripping. Note the perforated banding where the planks and the plywood met. When stacking clips are used on 4-bar panels, a tie element is needed to hold the opposing form panels together. Another method is to use Steel Dog® Stacking Spreaders.
