FSC Floor Span Connector
As an alternative to coil strap, our new FSC-Floor Span Connector,
connects upper floors to lower floors from the inside of the wall. The
convenient obround holes make installation in narrow wall cavities easy.
Installs with a 3⁄8" all thread rod, nut and washer (not included).
MATERIAL: See table
FINISH: Galvanized
INSTALLATION:
• Can be used on a single 2x stud.
• Threaded rod, washers and nuts are not supplied with the FSC.
• Use 3⁄8" threaded rod grade A307 or better, with matching nuts
and cut washers.
• FSC may be installed a maximum of 18" from the sill or
top plates.
• Drill 1⁄2" to 3⁄4" diameter hole through the plates for threaded rod access, hole should be located approximately 1 1⁄2" away from
the face of stud used for FSC attachment.
• Nails can be installed up to 30 degree angle with no reduction
in capacity.

1.The factored resistances have been increased 15% for earthquake or
wind loading with no further increase allowed; reduce where other loads govern.
2.Resistances are based on a minimum lumber thickness of 1 1⁄2".
3.Standard cut washer is required with the 3⁄8" all thread rod.
4.FSC’s shall be offset no more than 3" horizontally from each other.
5.NAILS: 10dx1 1⁄2 = 0.148" dia. x 1 1⁄2" long.
See pages 22-23 for other nail sizes and information.
DSP/SSP/SP/SPH/RSP4/TSP Stud Plate Ties
This product is preferable to similar connectors because of
a) easier installation, b) higher capacities, c) lower installed cost,
or a combination of these features.
The Stud Plate Tie series offers various solutions for connecting
the stud to the top and bottom plates. All models can be used to make a connection
to either the top or bottom plate, and several are suitable for double top plates
and studs.
MATERIAL: DSP/SSP/SPH—18 gauge; TSP—16 gauge; all others—20 gauge
FINISH: Galvanized. Some products available in ZMAX® coating;
see Corrosion Information, pages 14-17.
INSTALLATION: • Use all specified fasteners; see General Notes.
• TSP/DSP/SSP—sill plate installation-fill all round holes.
• TSP/DSP/SSP—top plate installation-fill all round and triangle holes
• SP1/SP2—one of the 10d common stud nails is driven at a
45° angle through the stud into the plate.

1.Factored resistances have been increased 15% for short term loading; no further increase is allowed.
Reduce values by 15% for standard term loading.
2.RSP4 factored lateral resistance is 345 lbs (1.53 kN) D-Fir-L and 245 lbs (1.09 kN) S-P-F for F1 direction.
The factored resistance in the F2 direction is 175 lbs (0.78 kN) D.Fir-L and 125 lbs (0.51 kN) S-P-F.
These values apply to both single and double plate applications.
3.When cross-grain bending or cross-grain tension cannot be avoided, mechanical reinforcement to resist
such forces should be considered.
4. Tabulated values for SP4, SPH4, SP6, SPH6, SP8 and SPH8 assume loads are applied through the centre
of the stud or plates (concentric loading). For applications where the load is applied to the connector through
one side of the stud or plates (eccentric loading) multiply the tabulated values by 0.50.
5.NAILS: 10d = 0.148" dia. x 3" long, 10dx1 1⁄2 = 0.148" dia. x 1 1⁄2" long, 8dx1 1⁄2 = 0.131" dia. x 1 1⁄2" long.
