Furnace Filter Swing-Aside Spring Retainer Clip
A 16 mm wide flex-finger clip that screws next to a furnace or return-air filter slot with one #8 or M4 screw (4.5 mm hole). It holds filters up to 24 mm thick (standard 1" nominal) with a sprung pressure nub, and the lift lip at the tip lets you flick it aside without tools when you swap the filter. It replaces the lost or broken sheet-metal turn-buttons on filter doors. The finger flexes in the layer plane, so it won't split along layer lines. Overall size is 70 x 32 x 16 mm.
Storm Door Insert Two-Reach Turn Button
A replacement turn button for the swing clips that hold glass or screen inserts in aluminum storm doors and windows. It is 56 x 16 mm and pivots on a #6/#8 or M4 screw through a countersunk 4.5 mm hole. The two arms reach different depths, 2 mm and 5 mm above the frame face. Turn whichever arm matches your insert onto the panel, and the chamfered edges ride up onto the panel as you turn it. No discontinued OEM clip is needed.
