Key Features
RKS sliding rails
RKS-01 and RKS-04 fit mounting depths of 553–834mm. RKS-02 fits 610–890mm, while RKS-03 fits 670–940mm. These kits have different system compatibility; select the matching model in Specs.
RKS-02 for current systems
RKS-02 supports RS1226+, RS1226RP+, RS826+, RS826RP+, PAS7700 and other systems listed in Specs. Match both the system model and rack measurements.
RKS-03 supplied with selected systems
HD6500, RX6025sas and RX6022sas include RKS-03 rails. Purchase a separate kit when you need a replacement or spare.
RKM114 fixed rails
Supported systems fall into two mounting-depth groups: 570–720mm or 570–810mm. RS1226+ uses the 570–720mm group. RS1226RP+ requires a different rail kit.
CMA-01 cable management
CMA-01 organises rear cables on RKS-01, RKS-02 or RKS-03. Allow at least 450mm post width, 125mm mounting-post depth clearance and 41mm height clearance.
Check before ordering
Use the model lists and mounting requirements in Specs to choose the correct accessory. Contact ACE with your Synology model and rack dimensions if you need help selecting.
Summary
Choose the accessory matched to your system, rack depth and mounting holes. Rails and the cable arm are sold as separate options, allowing you to order the part your installation requires.
Synology RKS Rail Kits RKM114 Rails and CMA-01 Cable Arm
Synology rack accessories are model-specific and must also fit the cabinet. The four RKS sliding rail kits have different supported systems and mounting-depth ranges. RKM114 is a fixed rail solution with two compatibility groups, while CMA-01 manages cables on selected sliding rails. The information below separates these configurations to help prevent ordering the wrong kit. Select one configuration as required; rails and cable management arms are separate accessories.
