H clips are also necessary for other wood panel thickness and span combinations.
How to install h clips on roof sheathing.
Ventilate the roof according to current building codes step 3.
Properly fasten panels including fastening and spacing hints step 4.
Nail the panels to the rafters with 8d common nails spaced 6 inches apart on the ends and 12 inches apart in the middle.
Once you ve spaced out where you are going to attach the clips they are ready to be attached.
Hammer in the clip to the parallel beam using 2 5 inches 6 4 cm nails.
For 24 inch centered framing position two clips equally spaced between rafters or joists approximately 8 inches apart.
This process starts with nailing them into the parallel beam.
Keep nails 3 8 inches.
One or two h clips will often allow a longer span between roof trusses rafters.
These nails go through the base plate of the clip.
The h shaped fins slide over the plywood until the middle connecting section is against the plywood s edge.
Check the nailing surface is level step 2.
A low slope roof below 2 12 pitch at the same span is an exception however and an h clip is specified.
Grip h clips are designed to make installing roof deck sheathing easier and faster with better spacing.
For 16 inch centered framing place the clip at the approximate middle point between each perpendicular framing member.
