A handle assembly includes a handle, a handle seal recess, and a hub engaging portion. A hub has a lock receiving surface and a handle engaging portion. A shaft is receivable within the hub and has first and second ends, the first end engaged with the handle, and the second end rotatable by rotating the grasping portion of the handle. A V-ring is disposed within the handle seal recess and engages the hub to prevent moisture ingress between the handle and the hub. The hub has a seal recess and an X-ring and an O-ring disposed therein to seal against the shaft to prevent moisture ingress between the hub and the shaft. Axial pressure applied to the O-ring by the hub engaging portion of the handle causes the O-ring to press against the X-ring to force at least one lobe of the X-ring against the central portion of the shaft.

Receptacle locking devices are disclosed. A receptacle locking device having a contact arm and a pivoting feature can be pivoted from a first, unlocked position to a second, locked position, wherein the contact arm prevents opening of the receptacle door when the locking device is in the second, locked position.

A safety stop device for limiting the movement of a window or sliding door that is fitted with a glass pane. The safety stop has a housing with a top plate. The top plate is flat. Support walls extend from the top plate and terminate in a common plane. A protected area is defined between the support walls and under the top plate. A suction cup is disposed within the protected area. A suction control assembly is coupled to the top plate. The suction control assembly selectively controls air pressure within the suction cup when the suction cup is engaged with the glass pane.

A safety bolt device comprising: a drop down bolt, the drop down bolt comprising: a cross-member; a first vertical pin attached to a first end of the cross-member; a second vertical pin attached to a second end of the cross-member; a door receiver configured to receive the first vertical pin, the door receiver comprising: a bolt; a jamb receiver configured to receive the second vertical pin, the jamb receiver comprising: a pin; where the door receiver is configured to attach to a door, and the jamb receiver is configured to attach to the door jamb of the door, and where the safety bolt device is configured to prevent the door from being opened when the drop down bolt has been dropped into the door receiver and the jamb receiver.

Embodiments of a cylinder lock include a cylinder lock case provided with a hollow interior. A knob key assembly is integrally formed with or secured to a spindle and maintained within the interior of the cylinder lock case. The knob key assembly includes a knob at one end and a locking element head at the other end. Embodiments of the knob key assembly further include a head nestable within a cradle of the spindle, wherein openings in the head and the cradle are aligned and are further alignable with a lateral opening in the cylinder lock case. Rotation of the knob permits the openings in the head and the cradle to come into or out of alignment with the opening in the cylinder lock case, while also rotating the locking element head between a first position where it can be removed from a lock structure and a second position where it cannot be removed.
