Because of the taper in the arms 12 , the H clip 10 can conveniently accommodate building material 11 sheets of a variety of thicknesses. Plywood clips connect the panel edges of plywood, thus reinforcing the stability of the 2 pieces of plywood by ensuring they don't shift and become uneven over time. In summary, H-clips have the ability to decrease deflection in wood panels and reduce the costs required by a building project.

If you have a sheet that's just a hair short/long, instead of cutting it, you can pull the nail on that rafter and push or pull the rafter until the end of the sheet is centered on it. Even if they are not required, we highly recommend H-Clips to improve the longevity and durability of your roof sheathing.In a preferred version, the H clip 10 is made of a flexible material such as nylon, plastic or other polymeric compound that can adjust to a specified range of thickness of the various building materials 11. Therefore, the ends 13 of the arms 12 exhibit some resistance to a complete parallel relationship between the arms 12 . For example, the typical H clip 10 designed for building material sheets of ±2 inch thickness can also accommodate sheets of 7/16 inch thickness. Inspectors should be concerned with safety and system defects that result from the lack of H-clips, but should not become encumbered by various code requirements.

As illustrated, the spacing bar 14 can also include a thickened area 19 to assist in air circulation between the sheets of building material 11. Clips are designed to be placed in between two rafters to minimize the span, in other words they are meant to almost serve as an additional rafter. each arm 12 includes a ski-shaped splayed prong or lead-in 16 connected to the end 13 by a living hinge 18 . But I’m not aware (maybe I’m wrong) that the span rating is increased by the use of ordinary plywood clips at this time.Another tip, if your rafter spacing is 24" instead of 16" stand on the sheathing over the rafters, not in between. I could be wrong but I thought the directional arrows only applied to roofs and floors (across the rafter/joist). This provides uniformity to the surface or structure being constructed, and frees the installer from having to estimate the proper expansion gap between each piece of building material 11.

the contoured face 20 of the lead-in 16 rotates on the hinge 18, as illustrated by reference number 17 in FIG.In this manner, the tapered arms 12 allow the H clip 10 to be used with materials 11 of a variety of thicknesses.

I believe there is a code requirement to nail all edges of wall sheathing but I am wondering if there is an exception if H clips are used. Sizes To Fit Your Panel Edges: We offer these in 7/16, 15/32, 1/2 inch sizes, ensuring these will be a snug fit for your roofing or walls.Further, the tapered arms 12 provide a necessary degree of flexion for use in applications where materials 11 of different thicknesses are used. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . If you’re fastening 1/2-inch or 5/8-inch Zip System roofing panels to rafters or trusses on the typical 16-inch or 24-inch spacing, H-clips aren’t needed. IIRC when all edges were nailed it did not make any difference to the strength, or maybe just a minor difference, if panels were vertical or horizontal.
