Product Overview
The HySecurity MX001745 Limit Plate and Blocks Assembly is the replacement limit adjustment hardware used on compatible SwingSmart DC swing gate operators. This assembly gives the operator a clean mechanical reference point for setting and holding the open and close travel limits. When the original limit plate is bent, the blocks are damaged, or the hardware is missing, the gate may have trouble stopping consistently at the correct position.
This is a small part, but it matters during setup and service. The limit plate and blocks work with the operator limit system so the control board can recognize travel positions correctly. A worn or misadjusted limit assembly can lead to overtravel, nuisance limit errors, inconsistent stopping, or repeated service calls after an otherwise good operator repair.
The assembly is commonly supplied as a complete service kit with the limit plate, two limit blocks, and mounting hardware. The individual pieces are generally not treated as separate replacement parts, so this kit is the practical replacement when the installed assembly is incomplete or damaged.

Technician Note
After installing this assembly, the operator limits should be reset and tested through several full open and close cycles. Do not assume the previous limit position is still correct after replacing limit hardware.
Before Ordering
- Confirm the operator is a SwingSmart DC model
- Compare the existing limit plate and blocks to the replacement assembly
- Check for bent brackets, loose hardware, damaged limit switches, or gate binding
- Have the operator manual available for limit adjustment after installation
Important Ordering Warnings
- This is not a control board, limit switch, or full actuator assembly
- Do not use this part to compensate for a gate that is out of level, dragging, or mechanically binding
Professional Advisory
HySecurity gate operator repairs often involve moving gates, stored energy, high voltage, batteries, and monitored safety devices. Electrical diagnosis and any unsafe gate movement should be handled by a qualified gate technician. Never bypass required entrapment protection or limit controls to keep an operator in service.
Product Questions and Answers
What does the MX001745 assembly do?
It provides the limit plate and limit blocks used by compatible SwingSmart DC operators to help establish the gate travel limits.
Is MX001745 sold as separate pieces?
Common listings describe it as an assembly with the limit plate, two limit blocks, and hardware, with the pieces not sold separately.
Will this fix a gate that overtravels?
It may help if the existing plate or blocks are damaged or missing, but limit switch condition, adjustment, wiring, programming, and gate mechanics should also be checked.
Does MX001745 fit SlideSmart or SlideDriver operators?
This part is written for SwingSmart DC applications. SlideSmart and SlideDriver operators use different assemblies and should be checked by parts diagram.
Should the limits be reset after replacement?
Yes. Limit settings and full gate travel should be checked after installation.
