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.
Drawers, modesty panels and return sections add work beyond attaching legs to a top. Include the full product configuration. Supplied mechanical fittings can be considered together, while unrelated storage units should be listed as additional items in the quote request.
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.
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.
