A protective guard for use with a fan or other mechanism includes main support members, perimeter support members, main screen members, and perimeter screen members with joints formed between the support members and screen members to inhibit access thereto. The support members define openings through which the screen members slidably extend to form the joints without welds. In one embodiment, the support members include unitary bars. In another embodiment, the support members comprise first and second bars having legs, which define recesses. When the upper and lower bars are attached, the recesses define openings through the support members for receiving the screen members.
