HES 003-0211-001 – Frequently Asked Questions

1) What exactly is the HES 003-0211-001 part, and what does it do inside the strike?
It's the locking cam spring for HES 300 Series electric strikes, part number 003-0211-001. Its job is to return the locking cam to the secured position and hold it there, which is what keeps the strike locked when power drops. It is not the cam itself and not a whole strike body, just the spring that drives the cam back.
2) Will this spring fit any HES electric strike, or only the 300 Series?
300 Series only. The 003-0211-001 is a direct-fit component for compatible HES 300 Series strike bodies and is not offered as a fit for other HES series. If your strike body is a different series, this spring is the wrong part.
3) Is this spring for a fail-secure or fail-safe electric strike?
Fail secure. The spring is set up so the cam stays locked with no power applied, which is what a security-critical opening needs. On a fail-safe strike the opening unlocks when power is lost, so if that's how your door is configured, this is not the spring for it.
4) My 300 Series strike buzzes and the latch no longer holds. Is replacing the cam spring the fix, or do I need a whole new strike?
If the symptom is a cam that no longer returns to or holds its secured position, the spring is the wear item and this is the targeted repair. Swapping the 003-0211-001 restores the OEM cam return force without pulling and replacing the entire strike assembly, which is the point of stocking it as a part. If the solenoid or the strike body itself is damaged, a spring won't correct that.
5) Is the 003-0211-001 a genuine HES part or an aftermarket copy?
Genuine OEM. It ships as an authorized HES/Folger Adam replacement part, manufactured to the original spring specification, so cam return force and fit match the factory assembly.
6) Is this a commercial-duty part or is it fine for a light residential application?
It's a commercial-grade component, built for the cycle counts electric strikes see in offices, schools, healthcare entries, government buildings, retail, warehouses, and multi-tenant residential entries. Nothing stops it working on a lighter door, but the spring is specified for high-use commercial access control.
7) I maintain several buildings with 300 Series strikes. Is it worth keeping the cam spring on the shelf?
For a fleet of 300 Series strikes, yes. The cam spring is a consumable that fails from cycling, and having 003-0211-001 in the truck or the shop turns a locked-open door into a bench repair instead of a full strike swap and rewire. It's stocked specifically as a replacement part for that reason.
8) Does ordering the 003-0211-001 require picking a finish, hand, or size?
No options to specify. The locking cam spring is a single configuration, ordered as 003-0211-001 with no handing, finish, or length choice, since it sits inside the strike body where none of that applies.
