The layers shall not be separ
32、ated bymore than the thickness of one longitudinal plus 14 in. The multiple layers shall be fastened together to form a single cage. If themultiple layers of a cage contain circumferential splices, the individual layers shall be rotated so that the splices are staggered.Allother specification requir
