Installation

Installation

Fasteners

On wood :

  • CNA annular ring shank nails
  • CSA screws
  • Refer to performance tables for relevant sizes

On concrete :

  • Chemical anchor: AT-HP resin + LMAS M12-150/35 threaded rod.

Installation

  • Install the CNA nails or CSA screws first, then set the ESCRFTC8.0 full threaded screws at an approximate 70° angle.  (A jig is recommanded for skewed screw installation - SSJ jig is available)
  • The possible screwing/nailing pattern are displayed below:
