Rebar Hook

Sigma rebar hooks allow easy single sided forming for large foundation pours  which greatly reduce the amount of tie length needed.

Please notify appropriate parties that you will be hooking on to the reinforcing cage and that proper precautions have been made to ensure structural integrity of the cage. Consult your individual project engineer before use.

400 Series Swivel Lag Bolt

The Sigma Swivel Lag Bolt (SLB) is a 5" x 3/4" lag bolt with our custom coil loop attached to allow a bit of movement when installing the fiberglass tie. The limitation is typically the wood in which the lag bolt is installed into so please consult the appropriate engineering guides when designing with the Sigma SLB.

To install the lag bolt, drill a pilot hole with a 1/2" diameter bit and at least a 4" depth. Use a lubricating film on the threads of the lag bolt to ease installation torque. Do not use the coil loop to install the bolt. Use the hex head.

Swivel Wing Nuts

Sigma's Cast Wing Nut and Swivel washer have been designed to be used as a single piece and maximize loads using just a single nut. The SWN are designed to be installed like traditional swivel wing nuts so no learning curve or special tools are required.

Water Stops

Sigma’s water stops are hydrophilic which means they swell and seal when they come into contact with water. A minimum of 3” cover should be used when using Sigma’s water stops to prevent concrete spalling. Sigma water stops are available for all sizes of Sigma Ties. This system is by far the easiest way to install water tight form ties in any waste water or water holding tank application.

EuroShe Coupler

Sigma Euro She Couplers are designed to be buried through the formwork in the concrete pour like a traditional she bolt. The length of the Euro Rod can be specified for a custom length she bolt tail. The length of the she bolt can be infinitely variable depending on the length of Sigma Tie Series which would be utlized. This is a great option for mass foundation pours as there is no need to patch and no worries about corrosion. It also works exceedingly well combined with the rebar hook for mass foundation pours.

Hex Coupler

Sigma Hex Couplers are designed with 1" coil rod and couple to the Sigma 800 and 1000 Series form ties. This coupler is designed to be used on the back side of aluminum beam style form systems, especially in radiused walls of water storage applications to greatly reduce the scrap fiberglass tie that would be generated. This allows the fiberglass to still be used as the inner rod, with a waterstop, to create a very inexpensive and water tight form tie.
