Locinox USA CLB-MAMMOTH – Frequently Asked Questions

1) Will the Locinox CLB-MAMMOTH bracket fit my chain link fence post?
The CLB-MAMMOTH mounts to round posts from 1-7/8in up to 4in in diameter, which covers the common terminal and gate post sizes on chain link fence. It is a round-post bracket, so a square tube or angle post is out of scope for it. Measure the post the closer will bolt to, not the gate frame, since that is the side this bracket clamps.
2) What gate frame size does the Mammoth chain link bracket work with?
Round gate profiles from 1-3/8in to 1-7/8in in diameter. That is the gate-side half of the mount. If your gate frame tube falls outside that range the bracket will not clamp it correctly, and neither will the included Dino hinge brackets.
3) Do I need extra hardware to mount a Mammoth gate closer on a chain link fence?
No separate trip to the fastener aisle. The CLB-MAMMOTH kit comes with all fixations plus a drilling jig for locating the holes on round tube, and brackets for the Dino hinge are in the box too. What you supply is the Mammoth closer itself and the drill.
4) Is the Locinox CLB-MAMMOTH bracket a gate closer, or does it replace one like the Norton Rixson 1351?
The CLB-MAMMOTH is not a closer. It is an aluminum bracket that mounts between a Mammoth gate closer and a round chain link post, sized for posts 1-7/8in to 4in in diameter and gate profiles 1-3/8in to 1-7/8in, with a drilling jig and all fixations included. The Norton Rixson Model 1351 is itself an exterior gate specialty closer rated for 250 lb gates, so it is the closing device rather than a mounting adapter. If you need the closing action, you are choosing a closer; if you already have a Mammoth and a chain link post, the CLB-MAMMOTH is what lets it attach.
5) The gate is a square tube frame on a square post, not round chain link. What should I use instead of the CLB-MAMMOTH bracket?
The CLB-MAMMOTH is built specifically for round profiles: round posts 1-7/8in to 4in and round gate profiles 1-3/8in to 1-7/8in, with a gap range of 1-3/16in to 2-1/16in. A square post and square gate frame fall outside what this bracket is shaped to clamp. For a square-frame exterior gate where you are specifying the closing device outright, the Norton Rixson Model 1351 is an exterior gate specialty closer rated for 250 lb gates and is a light duty unit. Confirm the gate leaf weight against that 250 lb figure before you commit.
6) Why can't I just bolt a Mammoth gate closer straight to a round chain link post?
A round post gives you no flat bearing surface, so the closer body has nothing square to sit against and fasteners pull unevenly under closing load. The CLB-MAMMOTH is the adapter that goes between the closer and the post, wrapping round tube from 1-7/8in to 4in and giving the closer a proper mount. The included jig gets the hole pattern right on a curved surface, which is the part that goes wrong when people improvise a bracket.
7) Does the CLB-MAMMOTH work with any gate closer or only the Locinox Mammoth?
It is cut for the Mammoth. The bracket's hole pattern, the supplied fixations and the drilling jig are all matched to that closer, and the extra brackets in the kit are for the Locinox Dino hinge. Pair it with a Mammoth and a Dino-hinged chain link gate; it is not a universal closer mount.
8) What are my options for a gate closer if I am not running a Locinox Mammoth on chain link?
For gates that are not round-tube chain link, ZenSupply carries the Norton Rixson Model 1351 exterior gate closer, a light duty unit for gates up to 250 lb, and the Norton Rixson Model 354, a double-acting interior gate closer for doors up to 75 lb. Those are self-contained closers rather than a mounting adapter, so they solve a different part of the job than the CLB-MAMMOTH does.
9) I manage a property with several chain link gates. Can I standardize on one Mammoth bracket across all of them?
Across gates within the range, yes. One CLB-MAMMOTH part number covers round posts 1-7/8in to 4in and gate frames 1-3/8in to 1-7/8in, so a mixed set of chain link openings usually falls under the same bracket. Walk the site and note post diameter, frame diameter and the post-to-gate gap (it needs to land between 1-3/16in and 2-1/16in). The openings that fall outside those three ranges are the ones that need a different mounting approach.
10) Can I use the Mammoth closer with the CLB-MAMMOTH bracket on an interior double-acting gate?
The CLB-MAMMOTH is a commercial chain link mounting bracket, aluminum anodized for corrosion resistance on exterior fence lines, and it clamps to a round fence post. Interior double-acting gates -- swinging both directions -- are a different problem. The Norton Rixson Model 354 is a double-acting interior gate specialty closer for 75 lb doors in the 350 Series, which is the configuration to look at for a light interior gate that has to swing both ways. Note the 75 lb figure: that is a much lighter leaf than a typical exterior chain link gate.
11) What is the difference between the Norton Rixson 1351 and the 354 when I am picking a gate closer?
They cover opposite ends of the job. The Model 1351 is an exterior gate specialty closer for 250 lb gates, carried as light duty in the 1351 Series. The Model 354 is a double-acting interior gate specialty closer for 75 lb doors in the 350 Series. So the split is exterior single-acting on a heavier leaf versus interior double-acting on a much lighter one. Weigh the leaf and settle whether it swings one direction or both before choosing. Neither of those is a mounting adapter -- if your closer is a Locinox Mammoth going onto a round chain link post, the CLB-MAMMOTH bracket is the separate piece that attaches it.
12) Will an aluminum gate closer bracket hold up outdoors on a perimeter fence?
It is anodized aluminum, which is the usual choice for exposed gate hardware because it does not rust the way a plated steel bracket does once the coating gets scratched during install. Locinox rates the part for commercial use, and it is aimed at perimeter fence, industrial access points, parking entries and similar exterior openings.
