Middle Atlantic VBK-PTRK26 VBK Series Magnetized Vent Blocker Kit for PTRK, 26" Deep, Black

Keep rack-mounted AV, security and IT equipment operating reliably by stopping hot-air recirculation with the Middle Atlantic by Legrand VBK-PTRK26 vent blocker kit. Designed for PTRK enclosures 26 inches deep, this magnetized vent blocker kit installs quickly without tools and includes pre-sized pieces for top, upper-side and rear door vents. By forcing heated air out through top-mounted exhaust fans instead of back into equipment intakes, the VBK-PTRK26 improves active thermal management, reduces hotspots and helps maintain consistent operating temperatures for surveillance, monitoring and networking gear.

The black, low-profile panels are engineered for professional environments and integrate seamlessly into standard racks, making them ideal for security closets, server rooms, AV cabinets and remote monitoring installations. Magnetized attachment simplifies service and reconfiguration while the kit’s fit-for-use sizing eliminates trimming or modification on-site. Whether you’re optimizing cooling for cameras, recorders, switches or servers, this vent blocker kit helps lower fan workload and supports system uptime. Add the VBK-PTRK26 to your next rack deployment to enhance thermal efficiency and protect critical equipment.
