A thimble assembly that includes an arch portion connecting a first leg portion to a second leg portion. The thimble assembly may also include a peripheral groove extending substantially along an outer surface of the first and second leg portions and the arch portion. The thimble assembly may also include a plurality of connectors extending from a first lip of the peripheral groove and connecting to a second lip of the peripheral groove. The connectors may traverse the peripheral groove across the first and second leg portions and the arch portion. The thimble assembly may include a length of cord with a plurality of strands that traverses the peripheral groove. The strands may enclose the connectors such that the strands are woven around the connectors. In one embodiment, the thimble assembly may include a wireless tension detector connected to the thimble that includes a sensor that senses radial expansion and contraction of the cord under tension. The wireless tension detector may include an alert signal to indicate when expansion and contraction of the cord is not within a predetermined range.
