Abstract: A leaf trap assembly is intended for ready installation in a downspout. The assembly comprises an elongated hollow body with a side wall opening and which attaches at each of its ends to downspout sections. A detachable door which covers the opening and a foraminous receptacle mounted for ready removal from the door are also provided in the assembly. The assembly is convenient to use in that it can be installed in the downspout near ground level. Additionally, separation of the door from the assembly and further separation of the receptacle from the door allows the receptacle to be cleaned in a very efficient manner.
