A one- to two-millimeter gap between the rim of a box and the underside of the lid is acceptable though 2 mm is a little too much. I would most likely shoot for 1mm. Why any gap? Wood surface swells first, before the inner wood, as this is the most exposed to the atmosphere and even with finish on it still absorbs though to a lesser degree. Rarely are environments regulated to perfect stability and in most family homes and offices, with an increased volume of occupancy can fluctuate markedly. That means that both the adjoining wood faces can come closer together albeit very fractionally. When it does, the swelling can cause the lid to bind and elevate the lid or door beyond the inner faces of the hinges leaving the box with an open gap on the edge opposite to the hanging side. Our task is to consider this possibility and then too anticipate such things and cater to them. Better the one-mil gap than for pride to say ultra-small or even no gap at all.
The size and weight of the door or window is yet another consideration to take into account when choosing what size & type of hinge to use. Usually two hinges placed top and bottom is sufficient. But for an extra heavy, tall, wide or high use door/window may require an extra hinge, or more, placed in the middle. This is commonly seen on commercial doors, but can apply to kitchen cabinets like pantry doors as well.
Instead of the swing bar, the crate is closed by two cover parts on top of which the next crate can be stacked. An advantage is that this cover can be sealed, preventing pilferage of produce. The crates with cover are up to 50 percent more expensive than the ones without a cover.
Because box lid hinges vary drastically in size, knowing what will fit comfortably on to use it. If you are in need of a box lid hinges that provides high quality support. However, you may decide you don’t need one so high.
For something with a high radial load, like a metal or wooden gate, a gate hinge may be in order. The hinge comprises an L-shaped bolt that inserts into a barrel that is attached to the gate. The bolt rotates in the barrel to swing the door open and closed.
Also known as a continuous hinge, the piano hinge gets its name from its original use on long piano lids. Piano hinges, however, are not just for pianos anymore. They are excellent anywhere a long hinge is needed, like on a storage bench or toy box.
Stitched crates are made of thin (3-4 mm) pieces of wood stitched together. Corner pieces, mostly triangular, provide the necessary strength to stack crates. This type of crate is mainly used for single journeys.
