A particle-free dockable interface with an interlocking latch is disclosed for linking together two spaces each enclosing a clean air environment and preventing the opening of the interface without the presences of two mating system components. The interface comprises interlocking doors on each space which fit together to trap particles which have accumulated from the dirty ambient environment on the outer surfaces of the doors. The interlocking latch is comprised of a latch spring and latch foot assembly coupled to a first one of the two clean air spaces and a mating door pull and port latch assembly coupled to the second of the two clean air spaces. The latch foot, door pull, and port latch assemblies are constructed so that interlock doors cannot be opened unless the first and second clean air spaces are properly aligned and mated.
