The HySecurity MX001933 is a replacement clamp handle kit used on HySecurity SwingSmart DC gate operators. Official HySecurity SwingSmart DC parts documentation lists MX001933 as Handle, Clamp, Replacement Kit for SwingSmart DC models.
This replacement kit is used in the SwingSmart DC clamp and arm connection area. It is commonly ordered when the original clamp handle is cracked, stripped, missing, difficult to tighten, damaged during service, or no longer holding properly. The clamp handle is a service part related to the taper clamp system, but it should not be confused with the full taper clamp assembly.
On SwingSmart DC operators, the clamp and arm connection must be set correctly so the gate arm remains secure during normal operation while still allowing the operator assembly to respond properly under certain impact or gate-strike conditions. If the clamp handle has failed because the clamp was over-tightened, slipping, seized, or forced, inspect the full taper clamp assembly, gate arm hardware, stops, and gate movement before replacing only the handle.

| Important Notes | Verify operator model, parts diagram, clamp handle condition, taper clamp condition, arm hardware, and gate movement before ordering. |
Depending on why the clamp handle is being replaced, the following related components may also need to be inspected:
A broken or stripped clamp handle is often a sign that the clamp assembly has been over-tightened, forced, or adjusted while another problem was present. Before replacing the handle, inspect the taper clamp assembly, hub surfaces, arm connection, stops, and gate movement. If the taper clamp is worn or slipping, replacing only the handle may not correct the problem.
The clamp handle should not be used to force a bad gate setup to work. A SwingSmart DC gate should move freely, hit stops correctly, and have proper arm geometry. If the gate is binding, slamming a stop, or putting heavy load into the arm connection, the new handle can fail again.
Clamp handle replacement involves the SwingSmart DC arm connection and moving gate hardware. Disconnect all power sources before service, including AC power, DC battery power, and any connected solar charging circuit. A swing gate can move unexpectedly if power remains connected or if the gate is under load.
After replacing the clamp handle, check the taper clamp setting, gate arm connection, travel limits, mechanical stops, and required safety devices before returning the operator to service. If the handle broke because the clamp was slipping, seized, or repeatedly over-tightened, the repair should be handled by a qualified gate technician.
The HySecurity MX001933 is a clamp handle replacement kit used on SwingSmart DC gate operators.
Official HySecurity SwingSmart DC parts documentation lists MX001933 as Handle, Clamp, Replacement Kit for SwingSmart DC models. Always verify the parts diagram before ordering.
No. MX001933 is the clamp handle replacement kit. The related full taper clamp assembly is commonly listed separately as MX001743.
Common causes include over-tightening, seized clamp hardware, worn taper clamp hubs, impact damage, poor gate stops, incorrect arm geometry, or a gate that is binding and overloading the arm connection.
Replace the full taper clamp assembly only if the hubs, clamp surfaces, or related hardware are worn, stripped, seized, or damaged. If only the handle is damaged, the handle kit may be the correct repair.
Do not assume it will fit. MX001933 is documented for SwingSmart DC. Other HySecurity operators should only be treated as compatible if the correct parts diagram calls for MX001933.
Inspect the taper clamp assembly, gate arm, clamp hardware, mechanical stops, operator mounting, gate hinges, and overall gate movement before installing the replacement handle kit.
