Typical FSS installation
Typical FS installation
Job site splicing of long trusses is made easier with Truss Field Splice
Kits. The FS and FSS (for scissors trusses) includes a pair of plates,
bolts, nuts, and a Splice Clip for top chord alignment. Allowable loads
are sometimes limited by tension in the net section of the wood.
Choose the bottom chord size and species that will satisfy the tension
requirement. Analyze tension in the web to determine the required size.
Materials: FS/FSS – See chart, bolts, and nuts included Splice
Clip – 12 gauge
Finish: FS & FSS – Primer; Splice Clip – G90 galvanizing;
Bolts – zinc plating
Installation:
• Use all specied fasteners. See Product Notes, page 18.
• Position the two trusses, center one splice plate on the bottom chords
and clamp in place for a drilling template. Install the Splice Clip at the
top truss plate and fasten with (18) 10d (0.148" dia) x 1-1⁄2" nails. Drill
through the bottom chord using splice plate as a template. Place splice
plate on each side and bolt the connection rmly.

1) Allowable loads shall not be increased for other load duration factors.
2) Allowable loads are based on the lesser of the calculated bolt loads and the calculated wood
tensile strength at the critical net section.
3) Wood tensile strengths are based on the Ft of 450 psi for S-P-F, 575 psi for DF-L, and
approximately 540 psi for SP; and increased by the size factors in accordance with the NDS®.
4) Bolts shall confrom to ASTM A 307 Grade A or better.
