How do you handle cable slack loops in a professional installation?

Trying to develop consistent slack loop standards for my crew. Right now everyone does it differently — some guys leave 6" service loops at the patch panel, others leave 24". At wall plates, some wrap a loop in the box, others don't.

What's your standard for cable slack at patch panels, at wall plates, and at horizontal cable transitions?

The reason for patch panel slack matters: when a port is damaged or needs re-termination, a 12" loop lets you cut, re-strip, and re-terminate at the same punch-down without disturbing the run. 6" often isn't enough to work with comfortably. I've seen well-intentioned "tight" installations that were a nightmare to service.

For fiber, service loop requirements are much larger — 1-meter minimum loops in fiber enclosures, 2-meter at splicing locations. Don't apply copper thinking to fiber slack.

My standard: at patch panels, 12-18" of service loop in the rack/cable management before the patch panel. At wall boxes, enough to pull the outlet out of the box for re-termination (6-8" looped inside the box). At transitions and pulls, enough slack at each end to re-terminate twice without re-pulling. TIA-568 recommends service loops for all these points but doesn't mandate a specific length.
