Send photographs of the existing joints, loose parts and instructions if the desk is partly built. A cross-threaded bolt or damaged insert can prevent correct tightening. Forcing the joint may make replacement parts necessary instead of allowing a simple adjustment.
Separate similar bolts using the instruction labels rather than appearance alone. A fastener that is too long can damage a desktop. Keep spare parts and packing information until the assembly is checked and any supplier shortage has been resolved.
Show the mounting method for a keyboard tray, shelf or cable tray. Accessories need to fit the particular desk and its instructions. Drilling new holes, supporting heavy equipment or adding unrelated brackets requires its own suitability review before inclusion.
The agreed service covers manufacturer-directed assembly of supported desk frames, tops and supplied furniture hardware. Exclusions: Electrical installation, cable relocation, custom joinery, motor/controller repair.
