    Sargent 758 – Frequently Asked Questions

    1) Can the Sargent 758 padlock be master keyed into our existing Sargent system?
    That's what the 758 is built for. It takes the standard 10 Line cylinder (catalog part no. C750-1) in a 6-pin configuration, so it keys into a Sargent master key system the same way the 10 Line locksets on your doors do. Keyways cover single key sections S, R, U and CR plus the L, R, H, C, A, B, K, N and V keyway families, so specify the keyway your system already runs. The cylinder pulls out while the padlock is unlocked, which makes rekeying a bench job rather than a lock replacement.
    2) What does key retaining mean on the Sargent 758, and will it stop my crew from walking off with the lock open?
    Key retaining means the key only comes out of the 758 when the padlock is locked. Leave the shackle open and the key stays captive in the cylinder, so a gate or cage can't be left unlocked with the key back in someone's pocket. That's the behavior you want on shared perimeter gates and tenant storage; it is the opposite of a non-key-retaining padlock like the Medeco 54515G XT, where the key comes out either way and the lock can sit open unnoticed.
    3) What shackle height do I need on a Sargent 758 for a chain link gate hasp?
    Three heights are offered: 1 inch standard, 2 inch (758-2) and 4 inch (758-4), all on an 11/32 inch diameter shackle. The 1 inch clears a standard hasp staple. For chain link gate hardware, a fence collar, or shackling through two links of chain, go to the 2 inch or 4 inch. Measure the total stack the shackle has to pass through before you pick, because the 11/32 inch diameter also has to fit the hasp eye.
    4) Stainless steel or hardened steel shackle on the Sargent 758 for an outdoor gate?
    Both are orderable on every shackle height, 1 inch, 2 inch and 4 inch. Stainless is the standard shackle and is the choice where corrosion is the problem: coastal sites, wash-down areas, anything that sits in weather year round. Hardened steel is the 758HS option and is what to specify where bolt cutters and attack are the concern, such as street-facing gates and yard equipment. If it's an exposed outdoor gate either way, note the shackle carries rubber shields to keep it from freezing up in winter.
    5) Do I have to specify keyed alike or keyed different when ordering Sargent 758 padlocks?
    Keying is a required selection: keyed different or keyed alike. Keyed alike is what a property manager wants when one key should open every padlock on a run of storage units or gates. Keyed different is the standard for anything under key control, where each padlock is its own change key inside the master system. There's also a keyway field so you can name the key section your building already uses, from S, R, U, CR or the L, R, H, C, A, B, K, N, V families, rather than getting a random keyway that won't operate on your masters.
    6) Is an ABUS 72/30 or 76/40 a substitute for a Sargent 758 padlock?
    They serve a different job. The ABUS 72/30 is an anodized aluminum safety padlock with a 1-1/4 inch body width and a 3/16 inch shackle diameter, and the ABUS 76/40 is a plastic-covered aluminum core padlock with a 1/4 inch shackle diameter and 1-37/64 inch width. Both are lightweight aluminum safety locks sized for lockout and tagout, where the point is that one worker holds the only key. The Sargent 758 is a 2 inch by 2-1/4 inch solid brass security padlock with an 11/32 inch shackle and dual ball bearing shackle locking, built to master key into a facility system. If the requirement is perimeter or storage security, the ABUS safety locks are not the same class of part.
    7) What is the closest brass-body padlock to the Sargent 758 if the keying system does not have to be Sargent?
    The Schlage KS23D/KS23F is the nearest brass-body equivalent. It is a brass padlock with a 5/16 inch diameter shackle, against the Sargent 758's solid one-piece 2 inch by 2-1/4 inch brass case with an 11/32 inch stainless steel shackle. The Medeco 5260 is the other brass-body option, with a 7/16 inch shackle diameter and M3 key technology. Where the 758 differs from both is the cylinder: it takes the standard 10 Line cylinder, catalog part C750-1, in 6-pin, so it master keys into an existing Sargent 10 Line system. The Schlage sits in the 20 Series and the Medeco 5260 on M3, so either one brings its own key system with it.
    8) Which padlock should be used on an outdoor gate where the Sargent 758 brass case is not wanted?
    The Medeco 521 G8R is the weather-exposed alternative: a weather-tight padlock with a solid stainless steel body, supplied less pop-out cylinder. The Sargent 758 handles outdoor duty differently, with rubber shields over the shackle to keep it from freezing in winter, but its case is brass in a US4 satin brass finish rather than stainless. Note that the 521 G8R ships without the cylinder, so a cylinder has to be specified separately, while the 758 comes as a keyed unit on the 10 Line cylinder.
    9) What replaces a Sargent 758 padlock when access needs to be audited electronically?
    The Medeco 54515G XT is the electronic option, an indoor/outdoor padlock with a 5/16 inch shackle diameter supplied with cylinder. It is non-key retaining, which is the operating difference a facility has to plan for: the Sargent 758 is key retaining, so the key comes out only when the padlock is locked and a gate cannot be left hanging open with the key in a pocket. The 54515G runs on the Medeco XT electronic platform rather than a mechanical master key system, so it will not key into a Sargent 10 Line master key hierarchy.
    10) Does the Sargent 758 padlock come with a chain?
    A 9 inch chain is available and has to be specified, catalog designation 758C. It's ordered as a chain or no-chain configuration against any of the three shackle heights and either shackle material. The chain is what keeps the padlock tethered to the gate frame or hasp so it isn't set down on the ground and lost after every opening, which is the usual failure on gates opened several times a day.
    11) How big is the Sargent 758 padlock body and what is it made of?
    Solid one-piece case measuring 2 x 2-1/4 inches, in a US4 satin brass finish. Body size matters when the padlock has to sit inside a shrouded hasp or a padlock guard, so check the pocket against those two numbers before ordering. Brass case, stainless shackle. For reference on scale, the ABUS 72/30 safety padlock is a 1-1/4 inch body width and the ABUS 74/40 is 1-1/2 inch, so the 758 is a substantially larger lock than an aluminum lockout padlock.
    12) How is the Sargent 758 shackle held closed, and can it be pried open?
    Dual ball bearings lock the shackle in the case, engaging it on both legs rather than a single locking pawl. That's the construction that resists a pry or shim attack on the heel of the shackle, and it means the shackle stays retained under load from both sides. Combined with the solid one-piece brass case, there's no seam to split. Verify the shackle seats fully on the first close after mounting, since a hasp that is out of alignment will hold the shackle short of the bearings.
    13) Can a Sargent 758 padlock be rekeyed in the field, and what parts do I need?
    Yes. Turn the key to unlocked and the 10 Line cylinder comes out of the case for rekeying at the bench, so a locksmith re-pins the cylinder instead of replacing the padlock when a key is lost or a tenant turns over. It's a 6-pin cylinder, catalog part no. C750-1. The service part for the cylinder retention is the Sargent 17-2632 tail piece and retainer pack, which covers both the 758 and 858 Series, and is worth stocking if you're maintaining a quantity of these across a portfolio.
    14) What is the difference between the Sargent 758 and the ABUS 74/40 for a 6-pin keyed padlock?
    Both run a 6-pin cylinder. The ABUS 74/40 is an insulated safety padlock with a 1/4 inch shackle diameter and a 1-1/2 inch body width. The Sargent 758 is heavier at 2 inch by 2-1/4 inch with an 11/32 inch shackle, and its 6-pin cylinder is the standard 10 Line, part C750-1, available in key sections S, R, U, CR and keyway families L, R, H, C, A, B, K, N and V. The practical split is key control: the 758 is specified when the padlock has to fall under an existing Sargent master key system, and the 74/40 when insulation and light weight matter more.
    15) Which padlock has the thickest shackle for a hasp with a large opening?
    Among the comparable brass and security padlocks, the Medeco 5260 carries the largest shackle at 7/16 inch diameter, followed by the Schlage KS23D/KS23F and the Medeco 54515G at 5/16 inch. The Sargent 758 shackle is 11/32 inch diameter and is offered in 1 inch, 2 inch and 4 inch heights, with a hardened steel shackle version available as 758HS. Shackle diameter has to be checked against the hasp eye before ordering, since a 7/16 inch shackle will not pass a hasp drilled for a 5/16 inch lock.
    16) Do any comparable padlocks offer a chain like the Sargent 758C?
    The chained configuration is particular to the Sargent 758, which is offered with a 9 inch chain by specifying 758C, in combination with any of the 1 inch, 2 inch or 4 inch shackle heights and either the stainless or hardened steel shackle. The ABUS, Medeco and Schlage padlocks in the comparable set are supplied as standalone locks. For a gate or valve cover where the padlock must stay tethered to the post, the 758C configuration is the one that answers it without adding a separate chain and second lock point.
    17) Is the Sargent 758 padlock rated for commercial use or is it a residential lock?
    Commercial. The 758 is a commercial door hardware item, and the build reflects it: solid one-piece 2 x 2-1/4 inch brass case, stainless shackle, dual ball bearing locking, and integration into a facility-wide Sargent master key system. It's specified for school and campus gates, industrial plant access, warehouse and storage security, municipal buildings and healthcare restricted areas, where key control across many padlocks matters more than the lock being cheap to replace.
    18) Is the ABUS T84MB/30 an alternative to the Sargent 758 for outdoor use?
    It is a much lighter part. The ABUS T84MB/30 Nautic is a black sleeve padlock with a 13/64 inch shackle diameter and a 1-17/64 inch body width, sold in a three-pack. That shackle is roughly half the diameter of the Sargent 758's 11/32 inch shackle, and the 758 body is 2 inch by 2-1/4 inch solid brass with dual ball bearing shackle locking. The T84MB/30 suits marine and low-security tethering; a commercial perimeter gate or warehouse hasp that has to sit on a master key system is the 758's application.
