Size: 63mmx54mmx50mm Large design for small spaces - Nobbees support is ideal for places where space constraints and/or flexibility are critical, such as kitchens, laundries, retail/grocery stores, recreational vehicles, ships, warehouses, industries, garages, maintenance warehouses, office/residential warehouses). It is applicable to the table feet or surfaces of folding table feet or DIY bed feet, folding rack items, folding table extensions, etc. For greater safety, these supports have a spring activated "positive lock" that provides stability by locking in the open position. When the worktable or working surface is not used, just press the latch and pull it down to obtain more workpieces. Load rate - 225 kg (500 lbs.)/pair. These load limits are for reference only and are not warranted, express or implied. These supports work best when applied to furniture feet or narrow, simple work surfaces. Wider spacing without leg support will result in reduced bearing capacity. The actual service conditions usually result in lower bearing capacity than the laboratory conditions. The package includes: 4 brackets, 16 screws fixed between the bottom of the workbench and the bracket.
