They can be made of metal wire, high impact poly carbonate (visor) or a combination of both.
Players who use a junior stick should check the spacing of the wire cage to the shaft of the stick. Some of the narrower shafts will pass through the openings in the cage & could result in injuries.
All cages should be checked to ensure the compatibility with the helmet. The cage should overlap the sides of the helmet & fully engage the helmet clips on the side when the player is wearing his helmet.
