What is the minimum extension above the finished floor for telecom room slots and sleeves?

Providing adequate clearance for cabling through floor openings and sleeves in a telecom room is essential. The minimum extension above the finished floor is 25 mm. This depth gives enough room for floor coverings (like carpet or tile) and any protective fittings (grommets or sleeves) so cables can pass through without being pinched or crushed, while not adding unnecessary height. A smaller extension (10 mm) risks insufficient clearance for finishes and fittings, potentially damaging cables. A larger extension (50 or 75 mm) is unnecessary and can create tripping hazards and extra intrusion without added benefit.
