The material of the Pets Dog Single Hook is usually made of stainless steel, alloy steel or aluminum alloy. Steel safety hooks are hard and heavy, suitable for connecting anchor points or in contact with sharp metal equipment, such as safety harnesses and lowers. The breaking load of the aluminum alloy shackle is not inferior to that of the steel product. The aluminum safety hook is relatively light in weight, and is suitable for connecting various equipments of personal protective equipment and carrying a plurality of spares. However, aluminum alloys are less resistant to cutting and should be avoided from hooking with other sharp metals when used.
Inspection and maintenance
The shape of Pets Dog Single Hook should be checked frequently. If it is deformed or cut, it should be discarded immediately and no longer used. If there is any intrusion into the lock, such as sand or iron filings, it should be cleaned immediately. Alloy steel safety hooks should be maintained with rust inhibitors and stored in special containers after use. If the safety hook is accidentally dropped from a high place (more than 2m) on a hard ground, its internal alloy composition may be seriously damaged even if it is not damaged, and should be discarded to avoid reuse.
