<p>The U-shaped bracket (1) has legs (2,3) with connections (4-8) for pipes to and from a water meter. A square hole in each leg accepts a bolt (10) whose shank has a short length (17) of square section. The angle brackets (13,14) have longitudinal slots in their legs (11,12). One foot (20) has a longitudinal slot (15) and the other foot (21) has a transverse slot (16). Either angle bracket (13,14) can be turned through 90 or 180 degrees in relation to the U-bracket by loosening the nut (19) a few turns to enable the square shank of the bolt to be withdrawn.</p> |
