HySecurity MX001746 Top Cap Cover Details
The HySecurity MX001746 is a replacement top cap cover used on HySecurity SwingSmart DC gate operators. This part covers the top section of the SwingSmart DC operator housing and is commonly replaced when the original top cap is cracked, missing, weathered, damaged by impact, or no longer fitting securely.
This is the top cap cover only. Public listings specifically note that the top cap knob is not included. If the knob, side covers, front cover, rear cover, latches, or hardware are also damaged or missing, those items should be inspected and ordered separately where required.
The top cap helps protect the upper portion of the operator enclosure from normal outdoor exposure. A damaged or missing cap can allow water, debris, insects, and sunlight to reach areas that should remain covered. On older SwingSmart DC operators, a brittle or UV-damaged top cap may crack when removed for service, especially if the knob or cover hardware has been overtightened.

Technician Note
The top cap is a protective cover part, but it still matters for operator reliability. A missing or cracked top cap can allow water, insects, dust, and debris into the operator housing. Before replacing the cap, check the knob, cover fit, cover latches, and mounting points. If the old cap cracked because the knob was overtightened or the cover was forced during service, correct that issue before installing the new cap.
If the operator has been running with the top cap missing or damaged, inspect the inside of the enclosure for water marks, corrosion, insect nests, loose wiring, and damaged electrical components before returning the gate to service.
Before Ordering, Confirm
- The required replacement part number is HySecurity MX001746.
- The operator is a compatible HySecurity SwingSmart DC model.
- The parts diagram calls for the MX001746 top cap cover.
- The top cap knob is still usable or is being ordered separately if damaged or missing.
- The 3-piece cover kit is not required instead of the top cap only.
- The front cover, rear cover, side cover latches, and enclosure hardware are not also damaged.
- The operator housing has not been bent or damaged in a way that prevents the top cap from seating properly.
- No water, insects, debris, or corrosion entered the operator while the cap was damaged or missing.
- You are ordering the top cap cover only, not a complete cover kit or operator enclosure.
Professional Advisory
Cover replacement is usually a straightforward service item, but the operator should still be powered down before removing covers or reaching inside the enclosure. Disconnect power as required by the service procedure before inspecting internal electrical components.
If the top cap was damaged by impact, vandalism, severe weather, or repeated water intrusion, inspect the full operator housing and internal components before returning the system to service. A replacement cover should not be used to hide existing electrical or enclosure damage.
