Sealing kit for NetShelter SX racks

This pack of 10 magnetic sealing strips fits APC NetShelter SX enclosures. It closes openings at the base and roof to stop hot exhaust air from recirculating into the cold aisle. The kit supports up to 10 racks and is compatible with part numbers AR3106SP, SMX750C, SMX750CNC, SMX1000C, SMX1500RM2UC, SMX1500RM2UCNC and SRT5KRMXLW-TW.

Simple magnetic installation

Each strip attaches magnetically to the rack frame without tools or fasteners. Installation takes minutes per rack and requires no drilling or adhesive. The main issue arises when strips are applied to surfaces with heavy dust or paint damage, which reduces magnetic grip and can leave gaps that defeat the seal.
