This sealing set is intended for sealing the gaps between the side plates or side skirts of connected racks. Use of this set ensures that no cold air can leak through to the back of the rack. The sealing set is available in 47U and 52U. If you want to use this set for smaller racks, it can be cut to the appropriate size. The sealing set for side plates is made of fire-retardant foam (UL94). To improve airtightness even further, the T-profile A002E-000002-000-1 is used between bottom frames to close the existing gap.
