Belden Inc. M57924B Cat5e Plenum Cable 1000 Ft

Product Description

The BELDEN INC. M57924B is a Category 5e plenum-rated network cable sold in 1000-foot pull quantities. Plenum-rated cable is constructed with a low-smoke, flame-retardant jacket engineered to meet the fire safety requirements of air-handling spaces such as dropped ceilings and raised floors. This cable is used to run structured data cabling through plenum air spaces where building codes mandate plenum-rated materials. Electricians and low-voltage cabling technicians install this product during new construction and retrofit structured wiring projects.

The M57924B is suited for horizontal runs in commercial and residential structured cabling systems where the cable pathway passes through a plenum air space. It is appropriate for voice, data, and network infrastructure installations that require compliance with plenum fire ratings. The 1000-foot reel length is the standard pull box quantity used by installers for large cable runs and commercial projects.

Installation Notes

Installation must be performed by a qualified low-voltage technician or licensed electrician in accordance with NEC Article 800 requirements for plenum-rated communications cable. De-energize any adjacent circuits before running cable through occupied ceiling or floor spaces. Avoid sharp bends that exceed the cable minimum bend radius, and do not staple or over-cinch the cable with tie wraps, as both practices can degrade signal performance.
