Locinox USA MAMMOTH-HD-9005 – Frequently Asked Questions

1) Do I have to order a left hand or right hand version of the MAMMOTH-HD gate closer?
No handing to specify. The MAMMOTH-HD is configurable on site for both left and right handed gates, so the same unit covers either swing. That matters if you are buying several for a property with gates swinging both ways, you stock one part number instead of two.
2) Do I need to buy a separate hinge with the Locinox MAMMOTH-HD, or is it a closer only?
It is both. The MAMMOTH-HD is a closer and hinge in one: the hydraulically damped Mammoth unit is the closing hinge at one pivot point, and the self closing Raptor hinge is included as part of the system for the second pivot. You are buying the complete two hinge set for the leaf, not a closer that mounts to hinges you supply separately.
3) Can a gate closer be mounted outdoors where it gets rain, sun and freezing temperatures?
The MAMMOTH-HD is built for exactly that. The mechanism sits in a weatherproof aluminum housing made for exterior use, and an active thermal system holds the closing speed constant as temperatures swing, which is the usual failure mode with outdoor closers, they slam in summer and stall in winter. Both the Mammoth closer and the Raptor hinge run on double bearings for low friction service outdoors.
4) Will the MAMMOTH-HD swing a gate a full 180 degrees back against the fence?
Yes, the MAMMOTH-HD is a 180 degree self closing system, so the leaf can open all the way back and still return on its own. Closing speed is adjustable and it finishes with a final snap action to drive the leaf into the latch rather than drifting short of it.
5) What should I use on a lightweight interior gate that has to swing both directions?
Not the MAMMOTH-HD. That one is a single direction 180 degree exterior system built for leaves up to 440 lbs. For a light interior gate that needs to push open either way, the Norton Rixson Model 354 is a double acting interior gate closer for 75 lb doors. Match the closer to the leaf weight, a heavy duty hydraulic unit on a 75 lb gate is the wrong tool.
6) Can the closing speed on the Locinox MAMMOTH-HD be adjusted after it is installed?
Yes. Closing speed is adjustable on the MAMMOTH-HD, and the patented hydraulic damping keeps that speed consistent regardless of the gate weight or how hard someone shoves the leaf. The final snap at the end of travel is separate from the general closing speed, so the gate can travel slowly and still hit the latch with enough force to catch.
7) Will a gate closer hold up on a public access gate where people abuse it?
The MAMMOTH-HD is built with a vandal and tamper proof design specifically for high traffic and exposed gate applications, with the hydraulics enclosed in the aluminum housing rather than left exposed. It is a commercial rated product, used on parking facility entries, warehouse and distribution centers, industrial access points and multi-unit residential complexes.
8) I have a light interior gate that swings both ways - is the MAMMOTH-HD the right closer?
For a light double-swinging interior gate, the Norton Rixson Model 354 is the match: it is a double-acting interior gate specialty closer for 75 lb doors. The MAMMOTH-HD is a 180 degree self-closing hydraulic closer and hinge in one for gates up to 440 lbs, configurable for left or right handed gates, and built for exterior use - more capacity and a different swing behavior than a 75 lb interior leaf calls for.
9) Does the MAMMOTH-HD replace both the gate closer and the hinge, or do I still need hinges like with a Norton Rixson closer?
The MAMMOTH-HD is a closer and hinge in one - it combines the hydraulically damped Mammoth closer with the self-closing Raptor hinge, and the Raptor hinge is included as part of the system, both with double bearings. The Norton Rixson Model 1351 and Model 354 are specialty closers, so the gate's hinging is handled separately from the closer. That changes what you order and what the fabricator preps on the post.
10) Will a light duty exterior gate closer hold up on a heavy commercial perimeter gate?
The Norton Rixson Model 1351 is a light duty exterior gate closer sized for 250 lb gates, which sets its working range. For a heavy commercial perimeter or industrial access gate, the MAMMOTH-HD is the heavy duty option, rated to 440 lbs with patented hydraulic damping that holds a consistent closing speed regardless of gate weight, an active thermal system for year-round speed consistency, and a final snap for reliable latching.
11) What finishes does the Locinox MAMMOTH-HD gate closer come in?
Two: Black Powder Coat and Silver Powder Coat. On a property where the gates are already black ornamental steel the black unit disappears against the frame; silver suits aluminum or galvanized fencing. Powder coat on an aluminum housing is what carries it outdoors long term.
