A hydraulic closer and dampener that can be removed and replaced by opening a post cap to then lift an internal closer assembly out of the top of an internally pivotable shaft inside a free-standing floor-mounted post. The remainder of the gate mechanism remains functional during such service. An automatic closing speed adjustment is easy to access and set. There are no external hinges, the gate pivots on an axis coaxial to the cylindrical post.

A bi-swing warehouse door latch system installs an electro-mechanical lock horizontally in the door casings overhead. Each has two catches to drop down on either side of the door. The doors are allowed to swing open when the respective catches are unlatched by a solenoid. The doors are not allowed to swing open when the respective catches are held latched by another solenoid and a teeter arm. Battery powered models produce brief pulses to put the catches in their locked states or unlocked states using a capacitor to store enough energy after power is lost to kick the solenoids. Utility powered versions can be configured to automatically relax into locked or unlocked states when power is lost. The doors are controlled to unlock when those with authorized access are recognized.
