Bend radius guide

A method comprising:

• providing a cable bend radius guide, the cable bend radius guide comprising:
• a flexibly rigid linear material of a predetermined length having a pair of corresponding bend radius markers separated by a predetermined distance along the predetermined length;
• and
• a restraint configured to fasten a first bend radius marker and a second bend radius marker of the pair of bend radius markers together to cause a portion of the flexibly rigid linear material between the first bend radius marker and second bend radius marker to generate a substantially circular loop having a bend radius corresponding to a cable's minimum bend radius;
• obtaining a cable requiring bending;
• conjoining the pair of bend radius markers by holding the first bend radius marker and the second bend radius marker together such that they are in proximity to each other and are adjacent;
• restraining the first pair of bend radius markers using the restraint;
• and
• bending the cable using the substantially circular loop as a reference such that the cable's bend radius is at least the minimum bend radius.
