Brass Desk Lid Hinge Supports act as both a hinge to open and close desk lids and as a support to hold desk lids in open flat position. Use on straight front and slant front desks where desk lid drops down to provide flat writing surface.
These hinge supports are intentionally made to not-open-flat when held in your hand.
Once installed, the weight of the desk lid adds leverage to the hinge support. This enables the desk- lid to hang properly and not sag.
Support should be mortised into bottom of desk interior and writing surfaces. Has a 180 degree throw once installed.
I have a mahogany desk from the '40s, with a fold down desk surface that has plaques me for years. The side hinges kept shearing across a screw hole, and I had then re-welded twice without success. Your brass hinges with a perpendicular reinforcing support fixed the problem for all time, and I could not be happier. They are so close to the originals, that visually, they melt right into the cabinet. Thank you for enabling me to reassemble a desk that was a wedding present to my father from his (somewhere he is smiling broadly, even though I stripped off all of the whitish antiquing he added to this desk in the early '60s)! Thanks again, from all three generations.
