PURPOSE: A replaceable insect screen is provided to facilitate the replacement of an insect screen without detaching a frame from a sash and to enable users to see through a window attached with the insect screen at low costs. CONSTITUTION: A replaceable insect screen (22) comprises a container, a fixing part, a handle part (32), a cut-out part (37), and a ratchet bar (18). The top of the container stores an additional insect screen (15). The insect screen is caught in the fixing part by every side. The handle part enables users to grip the insect screen to lower the insect screen after usage. The cut-out part removes the insect screen after usage. The ratchet bar tightens the insect screen. |
