It’s one of the simplest applications of metal connector plates. But, while the task seems obvious, there are several important elements to it that are missed sometimes.

ANSI/TPI1 requires the connection to be as tight as possible with no more than a 1/16” member to member gap and the plate should be positioned to provide adequate tooth count per the design drawing. Member to member gap is limited to 1/16” per section 3.7.6.1.
A Picture is Worth a Thousand Words The first photo illustrates an example of well-placed chord connectors on a floor truss (see Figure 1). The subsequent photographs illustrate several problems encountered when jigging or when equipment struggles to align key elements of the chord splice. Figure 1.

The second photo (Figure 2) shows the plate angulation issue. The connector is skewed and extends beyond the boundary of the truss profile.
