A strap-tensioning apparatus includes a frame, a handle connected to the frame, a reel supported on the frame, two ratchets secured to the reel, a first detent supported on the handle and biased to engage with the ratchets, and a second detent supported on the frame and biased to engage with the ratchets. The frame includes two walls each including a recess. The handle includes two walls each including a lobe. The first detent includes a chamfered tip. The ratchets can slide on the chamfered tip of the first detent to allow a strap to be reeled out when the chamfered tip of the first detent is in the recesses of the frame. The second detent is disengaged from the ratchets by the lobes of the handle when the chamfered tip of the first detent is in the recesses of the walls of the frame. |
