ABUS 65/40HB63 Solid Brass Padlock with Key, 1/4" Shackle diam., 1 17/32" Body Width

The HB63 is the long shackle version, and it gives 2-31/64 inches of vertical clearance with 55/64 inch horizontal clearance between the shackle legs. That vertical height is what lets you loop a chain, span a gate latch, or reach through a thick hasp that a standard-shackle padlock cannot close around. The narrow 55/64 inch horizontal gap is the limit, so measure the width of what you are passing through, not just the thickness.

Two keying options on the 65/40HB63: KA (keyed alike) and KD (keyed different). Keyed alike is what you want when one person or crew opens many locks, gates, meter boxes, storage cages, so a single key runs the whole set. Keyed different gives every lock its own key, which is right when separate tenants, vendors, or departments each control their own padlock. Property managers standardizing a site usually split it: keyed alike for maintenance-controlled openings, keyed different for anything a tenant holds.

The ABUS 65/40HB63 has a solid brass body with a 1/4 inch diameter shackle and a 1-17/32 inch body width. If the application calls for a thicker shackle, the Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle, and the Medeco 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter in satin chrome. A thicker shackle needs a hasp or chain link with a correspondingly larger opening, so confirm the hasp eye before you switch.

Yes, and corrosion is the reason to pick it. The body is solid brass, which doesn't rust, and the hardened steel shackle carries NANO PROTECT plating for corrosion resistance. The internal components are made from non-corrosive materials as well, so the cylinder isn't the weak point after a wet winter. That combination is why brass padlocks go on gates, sheds, cellar windows, and switchboards rather than a plain plated-steel lock.

The 65/40 sits in ABUS's middle tier: the 65/30 through 65/60 sizes are intended for goods of medium value or an average theft risk. With the long HB63 shackle it is aimed at chains, doors, gates, cupboards, lockers, tool boxes, cellar windows, sheds, and switchboards. For a suitcase, jewellery box, or cash box the smaller 65 bodies are the right call. For high-value goods or a high-risk opening, step up to a heavier padlock, and note that ABUS also builds a CS version of the 65 with a shackle guard that shields the shackle from cutting attack.

The ABUS 65/40HB63 uses a precision pin tumbler cylinder keyed on its own, either alike or different. The alternatives are built around a facility's existing key system. Sargent's 758 is a key-retaining padlock in US4 satin brass and the 858 is the non-key-retaining version with a stainless shackle; the Sargent 60-858-2 takes a removable core with a 2 inch stainless shackle, so it joins an existing SFIC master key system. Medeco's 5260 is a brass-body padlock with M3 key technology and a 7/16 inch shackle in satin chrome, and the Medeco 521 G8R is a weather-tight stainless steel body lock supplied less the pop-out cylinder. Go ABUS when you want a self-contained brass lock; go Sargent or Medeco when the padlock has to key into the building's system.

Yes, wrong lock for that. The 65/40HB63 is a mechanical key-operated brass padlock with a pin tumbler cylinder. For electronic control on an outdoor opening, the Medeco 54515G XT is an electronic indoor/outdoor padlock, non-key retaining, with a 5/16 inch shackle and cylinder included.

The ABUS 65/40HB63 is built for outdoor duty - solid brass body, hardened steel shackle with NANO PROTECT plating for corrosion resistance, and inner components in non-corrosive materials. The 2-31/64 inch vertical shackle clearance gives room for a gate chain or a thick hasp. If you want an all-stainless body instead of brass, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less the pop-out cylinder.

Key retaining means the key cannot be removed while the shackle is open, which is what many facilities require for locker and equipment lockout so a lock is never left hanging unlocked with the key in a pocket. If that is your requirement, the Sargent 758 is a key retaining standard padlock in US4 satin brass. The Sargent 858 and the Sargent 82-856 are non-key-retaining, both with stainless steel shackles, the 82-856 on a 2 inch by 2 inch brass case.

The ABUS 65/40HB63 measures 1-17/32 inch across the body with 55/64 inch of horizontal shackle clearance, so the hasp staple has to sit within that opening. Among brass-body alternatives the Sargent 82-856 is built on a 2 inch by 2 inch brass case, which is a larger footprint rather than a smaller one. Where clearance is tight, measure the staple and the gap between hasp leaves against the 55/64 inch horizontal figure before ordering either.

The body measures 1-17/32 inches wide. That matters when the hasp staple sits close to a door edge, a frame, or an adjacent lock, since the body needs that much lateral room to hang and to rotate for the key. On tight installs, check the space beside the staple before ordering, because a wider-bodied padlock will foul the jamb where this one clears.

The HB in 65/40HB63 marks a long shackle, and ABUS builds the 65 body in a range of shackle lengths. On the 65/40HB63 the usable vertical clearance is 2-31/64 inches. If you are locking a plain flat hasp where the shackle only spans two plates, a standard short shackle exposes less steel to a bolt cutter and is the better choice; the long shackle is for chains, gate latches, and anything with depth to reach over.
