Nail plate for CLT

Nail plate NPB255 has been developed to fix Timbr to Timber, Timber to concrete suports and CLT panels to CLT Floors or concrete support.

Very versatile, its installation is aided by centre line markings to indicate correct positioning of the connector

n = number of fasteners (CNA or CSA) on the top or bottom part of the plate. This number of fasteners has to be the same on both timber elements.

Distances to the edges of the timber must be checked.

For combinied forces it´s to check: \sum\frac{F_{i,d}} {R_{i,d}}\le1
