The top flange outlines a top opening therein, and has an arched and slotted inner peripheral surface with an open-ended slot that extends circumferentially therealong. The bottom flange has a circular inner marginal surface, which is created with an inward flange that extends integrally, radially and inwardly from a bottom end of the circular inner marginal surface and that defines a bottom opening therein. The insert member is inserted into the head portion of the spanner body between the top and bottom flanges. The insert member has a lower portion with a top surface, a upper portion th
The lower portion of the insert member has a side surface with two chamber units and abuts against the bottom flange for forestalling downward removal of the insert member from the head portion of the spanner body. The ratchet wheel is disposed rotatably inside the head portion of the spanner body. The ratchet wheel has a diameter-reduced bottom end that extends into the bottom opening in the head portion of the spanner body and that defines a circular shoulder, a toothed portion with a plurality of ratchet teeth, and a top end portion that’s formed with an annular groove. The circular
Further, it must be passed through the drum. Tie down strap must be pulled tight through the ratchet buckle on his hands, which allows for less than a fist width of slack in the belt. Finally, the handle can be controlled to take the remaining slack, until the object is bound is safe. It is important that the user does not tighten the belt, as this can cause damage to the facility, or to cause the ratchet mechanism of action.
