Don-Jo FBG-1-SQ – Frequently Asked Questions

1) What does a flush bolt guide like the Don-Jo FBG-1-SQ actually do on a pair of doors?
On a pair of doors, the inactive leaf is held by a flush bolt that throws a rod into the head frame or into the floor. The FBG-1-SQ is the guide plate that mounts on the door edge to keep that bolt rod aligned and moving straight as it throws and retracts. It is a support and alignment part, not the bolt itself, so it is ordered alongside or to repair an existing flush bolt assembly.
2) What size is the Don-Jo FBG-1-SQ flush bolt guide and how much does it offset?
The FBG-1-SQ measures 3-1/4 inches by 1-3/4 inches with a 5/16 inch offset. That offset is what sets the rod away from the door edge, so check it against the flush bolt rod you already have before ordering: a guide with a different offset will bind or let the rod wander.
3) Does the FBG-1-SQ come with the flush bolt, or do I need to order that separately?
The FBG-1-SQ is the guide only. The flush bolt assembly and its rod are separate items, so if you are building up an inactive leaf from scratch you need the bolt as well as the guide. If you are only replacing a bent or worn guide on a working bolt, the guide alone is the part.
4) Is the International Door Closers FG-1200 an equivalent to the Don-Jo FBG-1-SQ flush bolt guide?
Both are flush bolt guides, so they serve the same purpose: guiding and supporting the rod of a flush bolt at the door edge. The Don-Jo FBG-1-SQ is a square-corner guide measuring 3-1/4 inches long by 1-3/4 inches wide with a 5/16 inch offset, formed from 13 gauge (.095) steel. The International Door Closers FG-1200 is a standard flush bolt guide belonging to the FB-1200 series, so it is sized and shaped around that manufacturer's own flush bolt line. Before swapping one for the other, measure the existing cutout and the rod offset in the door edge, since guide plate length, width and offset have to match the prep you already have.
5) Is the Don-Jo FBG-1-SQ heavy enough for a high traffic commercial opening?
It is made from 13 gauge steel (.095), which is a heavy plate for a guide of this size, and Don-Jo classes the part as commercial rather than residential. That is the gauge you want on school, hospital and office corridor pairs where the inactive leaf gets worked constantly.
6) Is the FBG-1-SQ sold individually or in a box?
Don-Jo packs the FBG-1-SQ in a shelf pack of 50. That suits a maintenance shop or a contractor standardizing guides across a building full of door pairs rather than someone chasing a single repair.
7) My flush bolts are from the FB-1200 family. Should I use a Don-Jo guide or stay with the matching one?
If the flush bolts already in the doors are FB-1200 series, the International Door Closers FG-1200 guide is the one built to that series and is the safer match for rod alignment. The Don-Jo FBG-1-SQ is a general-purpose square guide in 13 gauge (.095) steel at 3-1/4 inches by 1-3/4 inches with a 5/16 inch offset, so it fits where that footprint and offset match the existing mortise. On a fleet of doors, pull one leaf, measure the guide pocket and the offset from the door face to the rod, and standardize on whichever plate matches that dimension across the building.
8) Is the FBG-1-SQ square cornered or radius cornered?
The SQ in FBG-1-SQ denotes the square corner version. If the mortise cut in your door edge was made with a radius router, a square corner plate will need the corners of the cutout squared off with a chisel to sit flat.
