- If it is an extremely narrow frame, you may need to consider a concealed door closer.
Is hydraulic better than pneumatic?
Hydraulic systems are capable of moving heavier loads and providing greater force than pneumatics, but pneumatics technology is cleaner. Leaks are of less concern with pneumatics, which can leak oil or hydraulic fluid. … The compressible gases used in the application of a pneumatics system are easy to store, and safe.
