CS14 Coiled Strap
CMSTC provides coined nail slots for lower profile when installed with 0.148" x 3 1/4" sinkers; it can be cut to length. CS are continuous utility straps which can be cut to length on the jobsite. Packaged in lightweight (about 40 lb.) cartons.
Gauge stamped on part for easy identification
Use all specified fasteners; see General Notes.
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 General Notes for Straps and Ties.
For lap splice and alternate nailing information, see tables below.
The cut length of the strap shall be equal to twice the “End Length” noted in the table plus the clear span dimension.
CMST only — use every other round hole if the wood tends to split. Use round and triangle holes for comparable MST loads, providing wood does not tend to split.
Lap splicing of coiled straps can be used to extend standard CMST12, CMST14 and CMSTC16 strap lengths longer than 40', 52 1/2' and 54' respectively, for designing continuous drag elements and diaphragm chord members. The Strap Lap Splices table below provides the minimum splice length (Lsp) and fasteners, within the splice length, to achieve the highest allowable capacity of the strap.
The allowable loads table provides allowable loads 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.
CS straps are available in 25' lengths; order CS14-R, CS16-R or CS20-R
For stainless steel, order CS16SS-R
