The covers in York are usually made of metal

 

and are rectangular

 

, square

 

, or circular

 

in shape.
As in other cities in the United Kingdom, a cover with a rather unique shape was found - a square cover with small rectangles at its corners

 

.

No colored or gilded covers were found in York. City emblems do not appear, apart from a cover/plaque marking a historic feature (the location where the wall of the Roman fortress once stood)

Diagonal covers were also found in York - square or rectangular covers composed of two triangles, where opening is done by lifting one of the triangles

In general, the design of the covers in York is not unique and follows designs typical of the manufacturer.

In many cases it is impossible to determine the purpose of the cover. In other cases, the word WATER (or its variations) appears on water covers

, the word GAS appears on gas covers
