CSHP High-Performance Coiled Strap

Product Details

Coiled steel straps are continuous utility straps which can be cut to length at the jobsite. The new patent-pending CSHP high-performance coiled strap features a raised embossment that makes it easy to install with a standard pneumatic framing nailer. This new tested feature provides improved performance — resulting in fewer nails, shorter straps and overall lower installed cost.

CSHP steel strapping is used in a variety of structural applications that make critical connections to resist earthquake and wind forces when they are imposed on structures.

Key Features

Designed to be installed with a standard pneumatic framing nailer
Achieves higher loads with fewer nails and shorter straps
Easy identification for proper installation for building inspectors

Material

See table

Finish

Galvanized (G90)

Installation

Use all specified fasteners; see General Notes.
The colored dot must be installed facing out.
Wood shrinkage after strap installation across horizontal wood members may cause strap to buckle outward.
Refer to the applicable code for minimum nail penetration and minimum wood edge and end distances.
The table shows the maximum allowable loads and the nails required to obtain them. Fewer nails may be used; reduce the allowable load as shown in the table notes.

This product is compatible with many power framing nailers and nails.

Use only nails with concentric, full-round heads that comply with ASTM F1667.
Do not use 28° wire-weld nails, or any nails with offset, clipped, or D heads.

Place the tool's nosepiece in the CSHP fastener feature. The outer ring of the power framing nailer nosepiece should fit within the outer ring of the fastener feature. Install a few nails to ensure nail install acceptance. The nail should be seated into the center of the CSHP fastener feature. Adjust air pressure or drive depth to achieve the correct nail placement. Operate framing nailers in single-drive, sequential-actuation mode only. Do not overdrive nails. See "Typical CSHP Installation" details in the image gallery.

Warning

This product is not compatible with all pneumatic framing nailers and nails. Do not use any tool that has been altered or modified. Before using the CSHP with any power framing nailer, you must determine whether the nailer is compatible with the CSHP product. If the nail is unable to be installed in accordance with the information above, or if the nail is not centered in the fastener feature, do not use that power framing nailer with the CSHP product. Wear eye and hand protection. Follow the manufacturer’s safety precautions when using any power nailer.

Load Tables

See General Notes for Straps and Ties.
Fasteners listed show the minimum required length.
Fasteners can be installed with standard framing nailer.
Calculate the connector value for a reduced number of nails as follows:
$\small \text{Allowable Load = }\dfrac{\text{No. of Nails Used}}{\text{No. of Nails in Table}}\times\text{Table Load}$

Example: CSHP18 in DF/SP with 12 nails total. (Half of the nails in each member being connected)

$\small \text{Allowable Load = }\dfrac{\text{No. of Nails Used}}{\text{No. of Nails in Table}}\times\text{Table Load}$
See below for alternate nailing and lap splice information.
Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.

Strap Lap Splices

See General Notes for Straps and Ties.
0.148" x 2 1/2" nails can be replaced by 0.148" x 3 1/4" nails. No other nail substitution is allowed for lap splices.
Refer to the applicable code for minimum edge distance and minimum end distance.
No strap modification is allowed and the splice must meet both the minimum number of fasteners and the minimum splice length.

Allowable Loads for Alternative Nailing

See General Notes for Straps and Ties.
Fasteners: Nail dimensions in the table are listed diameter x length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
