Norton Rixson 1639-689 – Frequently Asked Questions

1) Can a Hager 5919 pinion cap be used on a Norton Rixson 1600 Series closer?
No. The Hager 5919 is a pinion cap built for the Hager 5200 Series closer, while the Norton Rixson pinion cap is made for the Norton Rixson 1600 Series. Both parts do the same job - covering the pinion and keeping dust and debris out of the closer mechanism - but pinion caps are series-specific and are not cross-brand interchangeable. Match the cap to the closer series stamped on the body you are servicing.
2) The closer is leaking and the cap is cracked - do I need a replacement cap or a whole closer body?
A pinion cap is a protective cover only; it shields the pinion mechanism from dust and debris and does not contain the hydraulic valving or spring. If the closer body itself is damaged or leaking, you need a closer body assembly instead - for example, the Hager 5301 is a 5300 Series door closer body assembly with adjustable sizes 1 through 6. Replace the Norton Rixson 1600 Series pinion cap when the cover is the only failed part.
3) I manage a building with Hager closers, not Norton Rixson. Is there an equivalent pinion cap?
Not the same part. The Norton Rixson cap is series-specific to the 1600 Series. For Hager closers in the 5200 Series, the matching part is the Hager 5919 pinion cap. Match the cap to the closer's own brand and series; caps do not cross between manufacturers.
4) My closer is leaking and the cap is damaged. Do I replace the cap or the whole closer body?
A pinion cap is a cover only, so it will not stop a leak or restore lost closing force. If the closer body itself is failing, you are into a body assembly replacement, and for comparison a full body assembly like the Hager 5301 covers adjustable sizes 1 through 6. Replace the 1600 Series cap when the cap alone is cracked, lost, or letting grit into the pinion.
5) What finish does the Norton Rixson 1600 pinion cap come in?
One finish only: 689 aluminum, the standard painted aluminum finish used across commercial door closers. If your existing closer covers are a different finish, the cap will not match, so plan on it being visible at the pinion end.
6) Is the Norton Rixson 1600 pinion cap a finish-matching decorative cover like a full closer cover?
It is a component-level cap for the pinion area rather than a full-body cover, supplied in 689 aluminum finish, and it is designed to blend with the surrounding closer components. A full closer cover conceals the entire body; a body assembly such as the Hager 5301 is the complete working closer, not a cover at all. If you are trying to conceal the whole closer, the pinion cap alone will not do it.
7) Is this a commercial-duty part or something for a residential door?
Commercial. The 1600 Series pinion cap is classed as a commercial door hardware component and is used on closers in offices, schools, healthcare buildings, retail, warehouses, multi-tenant residential and government facilities.
