# CSHP High-Performance Coiled Strap

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 power 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 power framing nailer
• Achieves higher loads with fewer nails and shorter straps
• Easy identification for proper installation for building inspectors

• See table

#### Finish

• Galvanized (G90)

#### Installation

• Use all specified fasteners; see General Notes.
• "This Side Up" stamp 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.
• The cut length of the strap shall be equal to twice the “End Length” noted in the table plus the clear span dimension.

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.

• Lap Splicing
• Lap splicing of coiled straps can be used to extend standard strap lengths for designing continuous drag elements and diaphragm chord members. The Strap Lap Splices table provides the minimum splice length (Lsp) and fasteners, within the splice length, to achieve the highest allowable capacity of the strap.
•
• The Allowable Loads for Alternative Nailing table provides information for coiled straps when installed with different nailing schedules. The highest allowable load given for each model is limited by the steel capacity.
•
• The Engineer/Designer of Record must evaluate and determine the adequacy of the coiled strap’s lap splice and alternative nailing applications to meet their design loads.

#### Warning

This product is not compatible with all power 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.

#### Options

• CSHP straps are available in 25' lengths (add -R to model no)

#### Patent Information

• US Patent 11,098,478

2. Fasteners listed show the minimum required length.
3. Fasteners can be installed with standard framing nailer.
4. Calculate the connector value for a reduced number of nails as follows:

$\inline&space;\small&space;\text{Allowable&space;Load&space;=&space;}\dfrac{\text{No.&space;of&space;Nails&space;Used}}{\text{No.&space;of&space;Nails&space;in&space;Table}}\times\text{Table&space;Load}$

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

$\inline&space;\small&space;\text{Allowable&space;Load&space;=&space;}\dfrac{\text{12&space;nails&space;(Used)}}{\text{14&space;Nails&space;(Table)}}\times\text{1,540&space;lbs}=\text{1,320&space;lbs}$

2. 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.
3. Refer to the applicable code for minimum edge distance and minimum end distance.
4. No strap modification is allowed and the splice must meet both the minimum number of fasteners and the minimum splice length.
