GRANDMAX Cat5e Plenum 350MHz Solid Ethernet Cable 1000ft

In this review of the GRANDMAX Cat5e Plenum bulk cable, the bottom line is straightforward: this 1000 ft pull box is built for installers and IT pros who need a compliant, high-performance plenum-rated cable for permanent in-wall runs. The reviewer found the cable's ETL verified UL/CSA listing and 350 MHz testing to be the single biggest reasons to buy, as they provide verified headroom above standard Cat5e performance while ensuring code-compliant installation in plenum spaces.

Key Features

• CMP Rated: Plenum-rated jacket lets the cable be installed in air-handling spaces where fire and smoke characteristics matter.
• 100% Copper Conductors: Solid bare copper 24 AWG conductors deliver reliable signal integrity and lower attenuation compared with copper-clad alternatives.
• Tested to 350 MHz: Frequency testing above standard Cat5e gives additional bandwidth margin for gigabit Ethernet and overhead.
• ANSI/TIA-568-C.2 Compliant: Manufactured to industry wiring standards for predictable performance in structured cabling installations.
• 1000 ft Pull Box: Long continuous run reduces joints and splices for clean runs and faster deployment on larger projects.

Who It's For

This cable suits network technicians, electricians, and integrators installing voice and data cabling in commercial or multifamily buildings where plenum-rated products are required. It is aimed at projects that benefit from long continuous lengths and the assurance of compliance and third-party verification.

It is less appropriate for simple consumer desktop patching where stranded patch cable is preferred, or for environments that specifically require shielded cable; installers needing stranded, shielded, or waterproof outdoor-rated cable should look elsewhere.

Pros & Cons

Pros

• Plenum CMP rating allows safe installation in air-handling spaces under building codes.
• Solid 24 AWG 100% copper conductors provide consistent performance for long permanent runs.
• Tested to 350 MHz and ANSI/TIA-568-C.2 compliant, offering verified bandwidth and standards conformity.
• 1000 ft pull-box saves time and reduces splices on larger installations.

Cons

• Solid cable is not ideal for frequent flexing or patch-panel-to-device short runs where stranded cable performs better.
• Only UTP (unshielded), so it may not suit electrically noisy or high-interference environments requiring shielded cable.
