Installation

On the end of the ridge, use optional slots to secure the HRC50 and HRC1.81. Bend face flanges back flush with the ridge, and complete the nailing.
On face of ridge, adjust to correct height and install nails.
Obround nail holes ease rafter installation.
Optional diamond holes on the HRC range (except HRC44) are for installation convenience.
Double bevel cut hip members to achieve full bearing capacity.
May be sloped to 45° with no reduction in loads.
