5.177

扂鎻（上徒玷反切韻閉戶也字書小關礙門扇令不開也古文作扊又作𠂼下正作鎖音同蘇果反切韻鐵鎻）。

Door bar and lock [扂鎻] (The first character has the fanqie phonetic spelling 徒 + 玷; the Qieyun says to close a door; the character dictionary says a small bar that obstructs the doorleaves to prevent them from opening; the ancient script writes it as 扊 or 𠂼. The second character is properly written as 鎖, pronounced identically with 蘇 + 果; the Qieyun says an iron lock).
