Comparison

• Easy to use load tables correlate QuickTie anchor spacing directly to uplift reactions of trusses without requiring additional computations.

• The QuickTie is a single assembly from the top of the top plate to the foundation, providing a simple, unbroken load path for all uplift loads.

• Fewer system components means less computations required

• Since QuickTie’s are placed at variable spacings related to truss uplift reactions, they can be readily installed at optimal spacing as opposed to conventional systems which are generally selected for all locations using the most severe load case.

• The QuickTie system has no connections directly to the studs. Therefore, strength reductions in capacity of the system due to stud lumber selection is not necessary.

• End-of-shear wall hold-downs and hold-downs required at uplift load concentrations such as beams and girders. QuickTies handle both forces, and there is no need to have multiple systems for one building.

• QuickTie load table allowable loads are typically controlled by applying a safety factor of 3.0 to the ultimate (failure) load of the wall. The actual total maximum upward deflection at the mid point between the anchors at this load level is always less than ¼ inch and typically closer to 1/8 inch. This can be very favorably compared to the total aggregate movement potential of all of the stressed components in the load path of more conventional systems whose individual allowable load criterion generally allows 1/8 inch of movement for each component.

• The QuickTie system has undergone extensive, full scale testing under combined uplift and in-plane lateral shear loads. In comparative tests, the lateral movement of the QuickTie pre-stressed cable system performed equal to heavy conventional hardware and had less movement than a threaded rod anchor system!

• The QuickTie system is more efficient and cost effective in part because it utilizes the strength of the sheathing to distribute the truss uplift forces along the wall to the QuickTie anchors. This results in wider spacing of anchors which, in turn, results in both material and installation economy.

• The QuickTie system has been tested in full-scale wall uplift tests providing a higher level of confidence in system performance than systems where only individual system components have been tested.

• The primary component of the QuickTie, the wire rope, is subjected to considerable testing to assure that the performance characteristics are completely understood and established. Cables are tested for:
1. Strength 2. Elastic force/stretch characteristics 3. Inelastic constructive stretch and relaxation characteristics

• Furthermore, swaged samples of the wire rope/swage assembly are tested regularly as part of our quality control program.
