Sigma DG Swivel Lag Bolt product image

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.

Sigma DG Waterstop product image

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.
