Abstract: The present invention provides a plaster-box with improved handle attachment. The improved plaster-box is easy to operate and is user friendly. The plaster-box includes a handle attachment mechanism. The handle attachment mechanism removably couples a plaster-box handle to the top lid. The handle attachment mechanism includes a first clamp assembly and a second clamp assembly. The first clamp assembly includes a first screw member, a first clamp lever and a first clamping member. The second clamp assembly includes a second screw member, a second clamp lever and a second clamping member. The clamping force exerted by the first clamping member and the second clamping member tightens the handle with the top lid.
