Baldwin 0340190 – Frequently Asked Questions
1) Is the Baldwin 0340 Dutch door quadrant handed, or do I need a left and a right?
One part covers both. The 0340 quadrant is fully reversible and non-handed, so the same piece works on a left or right hand Dutch door. Handy if you're stocking for a building with openings swinging both ways, since you only carry one item.
2) How much clearance do I need between the two leaves for a Dutch door quadrant to work?
The bolt on the 0340 is 4.25 inches long with a 1.125 inch throw, so it needs 1.125 inches of engagement into the keeper across the gap between the upper and lower leaf. The keeper and pivot line up straight when the bolt is locked, so the two leaves have to be flush and hanging in plane, not one proud of the other.
3) Is a Dutch door quadrant a lock, or do I still need a latch on the door?
It's a bolt that ties the top and bottom leaves together, not a lockset. The quadrant locks the two halves so the Dutch door operates as one panel; you still need whatever latch or lock secures the door to the frame. Think of it as the equivalent of a surface bolt working between leaves rather than into a jamb.
4) How much face space does the Baldwin 0340 quadrant take up on the door?
Overall footprint is 4 x 4.75 inches, with a base plate of 1.5 x 2.5 inches. That's the area you need clear of any panel molding, glass stop, or rail edge on the inside face of the leaves. On a paneled Dutch door, lay it out on the stile or the meeting rail flat before you drill.
5) What comes in the box with the Baldwin 0340 Dutch door quadrant?
Each quadrant ships one per box with wood screws included. That covers a wood Dutch door out of the box. Nothing else is needed to mount it, though the wood screws supplied are for wood substrate, so a metal or composite leaf needs its own fasteners.
6) Will a Dutch door quadrant stay tight, or does it rattle loose over time?
The 0340 uses a self lubricating nylon washer that holds constant tension on the pivot, so the arm stays where you put it instead of flopping open. The castings are rated at double the tensile strength of ordinary sand castings. For a property manager dealing with a Dutch door that keeps drifting apart, that tension washer is the part doing the work.
7) Will the Baldwin 0340 hold the two leaves aligned if they've sagged slightly?
The strike is tapered on purpose, which pulls the top and bottom leaves into interlock as the bolt throws. That takes up small misalignment. It won't fix a leaf that has dropped enough to bind on the jamb, though, so rehang or shim the hinges first and let the quadrant handle the rest.
8) Is the Baldwin 0340 quadrant rated for commercial door traffic?
It's a residential grade part. For a light duty Dutch door in an apartment, a farmhouse style opening, or a hospitality pass through, it's the right item. For a high cycle commercial opening you would be looking at a commercial rated bolt instead.
