Reticle containers include a rotating latch including a spring. The spring provides force bringing the segments of the reticle container towards one another such that a reticle in the container is clamped between the container segments. The rotating latch can include a head as part of an assembly on one of a cover or a baseplate of the reticle container, with a slot configured to accommodate the head provided on the other of the cover or baseplate. The head can be disposed at an end of a shaft, with the shaft connected to a base, which is contacted by spring providing force such that the contact of the head with the other of the cover or baseplate provides clamping force to a reticle stored between the cover and baseplate.

A sealable hatch assembly may include a hatch lid and an elongated pocket on the interior side of the hatch lid and extending adjacent the perimeter. The elongated pocket may at least partially define a pocket width, and the sealable hatch assembly also may include a seal member received in the elongated pocket. The seal member may be configured to provide an uninterrupted seal between the hatch lid and a hatch extension coupled to the compartment adjacent the opening. The seal member may include an inner seal portion and an outer seal portion at least partially coating the inner seal portion. The inner seal portion may be elastically compressible, and the outer seal portion may be chemically resistant. The seal member may define a cross-section having an uncompressed dimension greater than the pocket width, such that the seal member is at least partially compressed as received in the elongated pocket.

A camera housing includes a simplified draw latch for securing a first portion and a second portion of the camera housing together. The draw latch can include a draw hook and a wireform mid-linkage. The draw latch enables a user to easily open and close a camera housing, and to establish an air-tight or water-tight seal between the housing portions for use in various activities, including scuba diving.
