Ives IVE-LG1-US2G – Frequently Asked Questions

1) Will the Ives LG1 lock guard work on a right hand and left hand door, or do I need to specify handing?
The LG1 is non-handed, so one part covers both swings and you order by finish only, not by hand. That matters if you're buying for a building with mixed openings: one line item covers every door. It mounts over the latch area on the door and pins to the frame, so the only thing you're matching is the finish to the rest of your hardware.
2) Does the Ives LG1 fit a mortise lock or only a cylindrical lockset?
Both. The LG1 measures 3 inches wide by 11-1/2 inches high, and that height is what lets it cover the latch area of either a mortise lock or a cylindrical lock. Before ordering, measure the flat area of the door face beside the lock: you need a clear 3 inch by 11-1/2 inch footprint clear of the lever, rose, or mortise trim for the guard to sit down properly.
3) What does the security pin on the Ives LG1 actually do that a plain latch guard does not?
The pin engages the frame, so when the guard is closed against the frame the door cannot be spread or pried away from the jamb at the latch point. A plain latch guard only shields the bolt from a shim or a pry bar at the gap. The LG1 does both: it covers the latch bolt area and it ties the door leaf to the frame. On an out-swinging exterior door where someone can get a bar into the gap, that is the difference worth paying for.
4) How does the Ives LG1 mount, and can someone unscrew it from outside?
It is through-bolted with carriage bolts and nuts, so the fasteners pass fully through the door and tighten on the inside face. There is nothing on the outside for a screwdriver to grab. That means the door has to be drilled through for the bolts, so plan on a template layout and access to both faces during install. It is not a peel-and-stick or wood-screw part.
5) Ives LG1 vs Don-Jo LP-307 latch protector - what is the difference?
Size and door type. The Ives LG1 measures 3 inches wide by 11-1/2 inches high and is non-handed, covering the latch bolt area on doors with mortise or cylindrical locks, and it carries an integrated security frame pin that prevents the door and frame from being spread apart at the latch. The Don-Jo LP-307 is a 2-5/8 inch by 7 inch 12-gauge steel latch protector specified for aluminum storefront entrance doors in an out-swing application. The LG1 covers roughly four and a half more inches of the latch area; the LP-307 is sized and handed for the narrow-stile storefront opening.
6) What guard covers the latch on a door with a panic exit device, since the Ives LG1 is made for mortise and cylindrical locks?
The Ives LG1 is described for use with mortise or cylindrical locks, covering the latch bolt area of the door and lock. Where the opening runs a panic device rather than a lockset, the Trimco PG8000 Series is a panic and latch guard line covering that application. Match the guard to what is actually latching the door: lockset latch bolt for the LG1, panic device hardware for the PG8000 Series.
7) Can a Don-Jo GLP-307 be used in place of an Ives LG1 on a hollow metal door?
They are not interchangeable. The Don-Jo GLP-307 is a 2-5/8 inch by 7 inch latch protector specified for aluminum entrance doors in an out-swing application. The Ives LG1 is a non-handed 3 inch by 11-1/2 inch guard in 12 gauge steel or 13 gauge stainless steel, through-bolted with carriage bolts and nuts, and it adds a security frame pin that engages the frame to prevent door-to-frame separation. On a commercial hollow metal opening with a mortise or cylindrical lock, the LG1 is the one built for that door; the GLP-307 addresses the aluminum entrance door instead.
8) What material and gauge is the Ives LG1 lock guard, and which one should I use outdoors?
Two constructions: 12 gauge steel, or 13 gauge stainless steel. The substrate options across finishes are steel, stainless steel, or brass. For exterior openings, loading docks, or anywhere with salt or washdown, take the 630 satin stainless version. The zinc plated 603 and 600 primer paint versions are the ones to use when the guard will be painted to match the door or lives under cover.
9) My door has an exit device, not a lockset. Is the LG1 the right guard?
No. The LG1 covers the latch bolt area of a mortise or cylindrical lock. A rim exit device latches into a strike on the frame and needs a panic guard shaped to that, not a lock guard. Look at the Trimco PG8000 Series panic and latch guards for that opening instead.
10) Do I need to change my existing lock to install an Ives LG1 lock guard?
No. The guard goes over the outside face of the door at the latch and does not touch the lock's internals, cylinder, or keying. Your existing mortise or cylindrical lock stays as it is. The install work is drilling the door for the carriage bolts and setting the guard so the frame pin lines up with the jamb.
11) Which latch protector works on both hands of door without ordering handed stock?
The Ives LG1 is non-handed, so one part number covers left-hand and right-hand openings and a facility can stock a single item across a building. The Don-Jo GLP-307, LP-307, and NELP-207 latch protectors are each specified for out-swing aluminum entrance or storefront doors, so the swing has to be confirmed against the opening before ordering. For standardizing across mixed hands on mortise and cylindrical lock doors, the non-handed LG1 keeps the stocking list to one line per finish.
12) Which latch guards are 12 gauge steel like the Ives LG1?
The Ives LG1 is built in 12 gauge steel or 13 gauge stainless steel. Among comparable latch protectors, the Don-Jo LP-307 is 12-gauge steel at 2-5/8 inches by 7 inches for out-swinging aluminum storefront entrance doors, and the Don-Jo NELP-207 is 12 gauge steel at 3-1/2 inches by 6.5 inches for out-swinging aluminum entrance doors. All three share the same 12 gauge steel body, so the decision comes down to door type, swing, and the coverage length needed at the latch.
13) What finishes does the Ives LG1 lock guard come in?
Six: 600 primer paint, 603 zinc plated, 606 satin brass, 612 satin bronze, 630 satin stainless steel, and 695 dark bronze. If you're standardizing a building, 630 is the usual match for stainless levers and push plates, 612 and 695 for bronze storefront and dark anodized aluminum, and 600 primer when the guard gets field painted to the door color.
14) Is the Ives LG1 lock guard rated for commercial use or is it a residential part?
Commercial. It is a 12 gauge steel or 13 gauge stainless guard built for exterior openings taking real traffic and real abuse, which is why it through-bolts rather than screws. Typical placements are back doors on retail and warehouse buildings, school and healthcare service entries, and multi-tenant residential exterior doors.
