VPA

Variable Pitch Connector

The VPA is an engineered one-piece connector for attaching I-joist rafters to wall plates.

  • The VPA is adjustable to slopes between 15° and 45° with a special interlock design indicating when the maximum pitch is reached. This product complements the versatile LSSU.
  • Designed for use with double 38mm top plates with a 50mm seat, which allows sufficient bearing area for most rafters.
  • No notching of the I-joist is required when using the VPA. This connector reduces the need for bevelled plates and toenailing. It has positive angle nailing to speed installation and to minimise wood splitting.
