GK insulators are suitable for all pipes 98 mm - 500 mm diameter.

Three segment sizes (GK1, GK2, GK3) can cope with all the differing pipe diameters - consequently you save on designated storage area.

The narrower central skid allows better access to the screws - consequently you save construction time.

With the size GK 3 the segments per ring are reduced - consquently you save on screwdriver work.
