Abstract: The present disclosure relates to a manhole for a gas-phase polymerization unit having a through-hole formed with a shoulder (28) matching a corresponding shoulder (38) of a plug of a closure member (30) operatively inserted in said through-hole. In some embodiments, the through-hole is closed with a minimum clearance (47) so that polymer particles do not deposit in the gap between the wall (10) of the unit and the plug of the closure member (30). In further embodiments, retrofitting of standard manholes using the manhole disclosed herein is performed.
