Marking and ducting system for underground cables - uses two-half duct with vertical projections which are terminated at ground surface levelThe cable duct is in two halves: a lower half and an upper half. Both halves have flanges to permit bolting of the two halves. The upper half has ...
Cable for the control, measuring and signal circuits of electrical equipment for fixed surface and flush-mounted installations,indoors and outdoors. Not suitable for installation directly in ground nor directly in concrete without protective ducting. Not for installatio...
Our proprietary PVC extrusion coating provides a molecular bond with the polyester scrim creating a very strong composition with adhesion typically 50-70% better than laminated fabrics commonly used for PCA ducting. The fabric backside is coated in the color black to reduce opacity and help slow th...
In various embodiments, an aboveground protective shelter can utilize an air ducting system and/or retractable stabilizers to resist movement of the shelter during a high wind event, such as a tornado, hurricane or explosion blast. If present, the air ducting system utilizes the reduced air pressu...
