ABSTRACT:
A bolt (42) is inserted threaded end (56) first upwardly through a first opening (68) within a lower arm portion (14) of a C-shaped saddle (12), then through an opening (70) in a lower end portion (34) of an insert (28), then through an opening (72) in the upper end portion (32) of the insert (28), and then through an opening (66) in the upper arm portion (16) of the saddle (12). The opening (68) is hexagonal in shape. A nut (44) is then installed on the bolt (42). The nut (44) has a small end portion (48) which is hexagonal in shape. The nut (44) is hand tightened and then is aligned with the opening (66) so that the small end portion (48) will drop into the opening (66). A wrench is then used on the bolt head (46) for rotating the bolt (42) for the purpose of drawing the nut (44) and the bolt (42) together and applying a clamping force on a pipe (26) which is within the saddle (10). A central portion (30) of the insert (28) bears on a portion of liner (24) which surrounds the pipe (26) an opposite portion of the liner (24) contacts a bight (18) portion of the saddle (12). The tightening of the nut (44) and bolt (42) pushes the central portion (30) of the insert (28) tight against the liner (24).
