ABUS 84IB/40 C Weatherproof Brass Padlock, 1/4" Shackle dia., 1 1/2" Width

That's what the 84IB is built for. The body is nickel-plated solid brass, the shackle is stainless steel, and the internal components are non-corrosive materials, so rain, salt spray and washdown don't seize the mechanism the way they do on a plated steel lock. It's classed as a commercial padlock rather than a residential one.

It's self-locking. Push the shackle down and it latches without the key, so a maintenance tech carrying one key for the whole property can close up a gate or meter box one-handed and move on. The key is only needed to open it.

Two keying options are offered on the 84IB/40: KA (keyed alike) and KD (keyed different). Keyed alike is what a property manager or facilities crew wants when a dozen gates, storage cages and utility boxes should all open on one key carried on the truck. Keyed different is right when each tenant, subcontractor or department has to be locked out of the others' spaces. Order all the keyed-alike locks for a site at the same time so they land on the same key.

The ABUS 84IB/40 is built for wet exposure with a stainless steel shackle and non-corrosive inner components. For the same outdoor duty from another maker, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, and the Medeco 54515G XT is an electronic indoor/outdoor padlock with a 5/16 inch shackle. The G8R answers the same mechanical weather question; the 54515G brings electronic credentialing to it.

The ABUS 84IB/40 is self-locking, meaning it locks by pushing the shackle down without a key, so the key comes out with the lock open. If you want that behavior spelled out in a Sargent, the 858 is a non-key-retaining padlock with a stainless steel shackle in US4 satin brass, and the 82-856 is non-key retaining with a 2 inch by 2 inch brass case and stainless shackle. The Sargent 758 is the key retaining version, which holds the key until the shackle is closed - the opposite behavior, and the one to avoid if crews need to walk away with the key.

The ABUS 84IB/40 is a precision pin tumbler padlock ordered keyed alike or keyed different. If a facility is standardized on removable cores, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, which lets the padlock join the same core system as the doors. That is a different keying approach than picking KA or KD at the time of order.

The 84IB/40 is a pin tumbler padlock supplied on ABUS keying, ordered keyed alike or keyed different. If the requirement is a padlock that runs on the facility's existing key system, that's a job for an interchangeable or removable core padlock instead: the Sargent 60-858-2 takes a removable core, and the Medeco 54515G ships with a cylinder. Those are the ones a locksmith can key into an established system.

The 84IB/40 has a nickel-plated solid brass body with a stainless shackle. Brass won't rust and takes plating well, and the plated finish handles ordinary weather exposure. Where a lock sits in constant salt or chemical exposure, a fully stainless body such as the Medeco 521 G8R, which has a solid stainless steel body, removes the plating from the equation entirely. For general exterior use on gates, sheds, and equipment, the brass body is the common choice.

No. The ABUS 84IB/40 body is nickel-plated solid brass, so the visible surface is nickel rather than brass tone. The Sargent 758 and Sargent 858 carry a US4 satin brass finish, which is the brass appearance. If matching the look of existing hardware matters on a storefront or entry gate, that is the distinction to check before ordering.

The ABUS 84IB/40 is a mechanical pin tumbler padlock keyed alike or keyed different, which controls access by who holds a cut key. Where a site needs credentials managed electronically, the Medeco 54515G XT is an electronic indoor/outdoor padlock, non-key retaining, with a 5/16 inch shackle diameter and cylinder. It covers the same outdoor exposure but moves the access decision from the key cut to the electronic credential.

The ABUS 84IB/40 uses a nickel-plated solid brass body with a stainless steel shackle. If the environment argues against brass entirely, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less the pop-out cylinder so the cylinder is specified separately. That last point matters on ordering: the G8R needs a cylinder decision the 84IB/40 does not.

If key retention is the deciding factor, specify it directly. Key retaining padlocks hold the key captive until the lock is closed again, which is how facilities stop a tech from walking off with an open lock hanging on a fence. The Sargent 758 is a key retaining padlock; the Sargent 858 and the Sargent 82-856 are non-key retaining. Buy on that spec rather than assuming it from the body style.
