Translation of "morroilo" into English

Nik ziztuan armairu baten goiko aldera igo nuen kamera, pisuko atea morroiloz itxi, aulki bat jarri eta komunean itxi ginen. Eskaileretatik entzun genituen builaka. Baina okertu eta 4.eraino igo ziren.

I quickly put the camera on top of a cupboard, bolted the apartment door, put a chair against it, and we locked ourselves in the bathroom. We heard them shouting from the stairs. But by mistake they went up to the 4th floor.
