Cal-Royal CRWRENCH – Frequently Asked Questions

1) What is the Cal-Royal CRWRENCH used for?
The CRWRENCH is a variable-sized hex wrench made for adjusting the CR3049HO arm used with Cal-Royal's CR441 Series door controls. It handles the fastener sizes on that arm, so a tech making field adjustments to arm tension and operation carries one tool instead of a set of loose hex keys.
2) Will the CRWRENCH work on door closers other than Cal-Royal's CR441 Series?
It is built specifically for the CR3049HO arm on the CR441 Series. If you are servicing another manufacturer's closer arm, this is not the tool to order. For closer arm parts from other brands, ZenSupply carries items like the Deltana DCHA1050 hold open arm for the DC10 closer and the Deltana DCCA4041 cushion arm for the DC40, each matched to its own series.
3) If the closer arm itself is worn rather than just out of adjustment, what should be ordered instead of the wrench?
The CRWRENCH only makes field adjustments to the CR3049HO arm on Cal-Royal CR441 Series door controls; it does not replace any worn component. When the arm assembly itself is the problem, the replacement has to match the closer brand and series. Comparable arm assemblies include the Deltana DCHA1050 hold open arm for the DC10 closer, the Deltana DCCA4041 cushion arm for the DC40 closer, and the Dorma 15323 1-1/2 inch offset bottom arm with cover, a standard duty part that is not fire rated. Confirm the closer series on the door before choosing among them.
4) For a hold open function on a fire or life safety opening, is the CRWRENCH the right part to order?
No. The CRWRENCH is a service tool for adjusting the CR3049HO arm on Cal-Royal CR441 Series door controls, so it has no bearing on how a door holds open. Hold open and fire/life safety function comes from the closer's arm or track hardware: the LCN 4040SEH-3038 is a hold open track in the 4000 Series, and the LCN 4040SE-3038 is a standard track for fire/life safety door closers in the 4040SE Series. Those are the parts that set the function on the opening.
5) How many versions of the Cal-Royal CRWRENCH wrench are there?
Just one. The CRWRENCH is sold as a single model with no size, finish, or handing choices to specify, so there is nothing to select beyond the part itself.
6) Does the CRWRENCH come with the CR441 closer, or does it need to be ordered separately?
The CRWRENCH is catalogued by Cal-Royal as a standalone accessory for the CR441 Series line, so it is ordered on its own. Maintenance departments standardizing on CR441 closers across a building typically add one per service kit rather than one per door.
7) Do I need more than one hex key size to adjust a Cal-Royal CR3049HO arm?
No. The CRWRENCH's variable-sized hex design covers the multiple fastener sizes found on the CR3049HO arm, which is the point of it, one tool rather than several standalone keys in the truck.
8) Is the Cal-Royal CRWRENCH interchangeable with closer arms like the Deltana DCCA4041 or DCHA1050?
No. The CRWRENCH is a variable-sized hexagonal wrench, a hand tool used to adjust the CR3049HO arm on Cal-Royal CR441 Series door controls. The Deltana DCCA4041 is a cushion arm for the DC40 door closer and the Deltana DCHA1050 is a hold open arm for the DC10 door closer; both are mounted door closer arm assemblies that become part of the installed hardware. A wrench and an arm serve different roles on the opening, so one never stands in for the other.
9) Is the CRWRENCH a commercial-grade tool or a homeowner item?
Cal-Royal classes the CRWRENCH as commercial. It is a service tool for professional installers and maintenance crews working on surface mounted door control hardware, not a consumer accessory.
10) Is the CRWRENCH a mounting accessory like the LCN 1260-18QF bracket kit or 1260-30 cush shoe support?
No. The LCN 1260-18QF is a quick fix bracket kit in the 1000 Series and the LCN 1260-30 is a cush shoe support built for 3-1/16 inch reveal compatibility in the 1260 Series; both are mounting components that stay on the door or frame after installation. The Cal-Royal CRWRENCH is a compact hand tool that stays in the technician's service kit and is used to adjust the CR3049HO arm on CR441 Series door controls.
