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.
A separately purchased desktop may not share the fixing pattern or supported dimensions of the base. Provide both product specifications. Do not assume that drilling extra holes or shortening the top is included in a straightforward furniture assembly quote.
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.
