Lit-Off Desarrollo, S.L. is a company based in Sabadell (Barcelona), founded in 1994 and specialised in identification, labelling and safety solutions for industrial environments. This catalogue presents the range of lockout/tagout (LOTO) products we distribute in Spain and Europe: safety padlocks, lockout devices for valves, circuit breakers, plugs and controls, lockout hasps, tags, boxes, stations and kits.
A LOTO procedure consists of isolating all energy sources of a machine or installation (electrical, pneumatic, hydraulic, mechanical, thermal) before maintenance work, physically locking the isolation points with a device that only the person who applied it can remove, and marking it with a tag. Hazardous energy is present in every plant; accidents caused by unexpected start-up are prevented by a properly applied lockout.
All references in this catalogue are available in the keying options indicated (KD, KA, MK, GMK) and, on request, with laser marking of your logo or numbering and tags in the language you need. Tell us about your application and we will advise you on the right configuration.
How to use this catalogue
Each product is identified by its reference (Ref.). Please quote it when requesting an offer.
Padlocks: the reference prefix indicates the keying system (KD = keyed different, KA = keyed alike, MK = master key, GMK = grand master key).
Dimensions in drawings are in mm unless stated otherwise. Images are for guidance only.
Laser marking of logos, numbering of keys and bodies, and tags in your language: on request.
Lockout devices complement a documented LOTO procedure and staff training; they do not replace the risk assessment of each installation.
Safety padlocks for lockout/tagout (LOTO), with a reinforced nylon body and a steel, stainless steel, insulating nylon or cable shackle. Available in different shackle lengths, body shapes and eleven colours, with keyed alike, keyed different, master key and grand master key systems.
Key retention: the key cannot be removed while the shackle is open.
Non-conductive cylinder: safer operation, as it prevents electricity passing from the shackle to the key.
Reinforced nylon body that gives the padlock strength and does not deform easily. Both the steel-shackle and the non-conductive-shackle padlock withstand temperatures from −20 °C to +120 °C.
Widely used in the chemical, electrical and automotive industries, among others.
With rewritable warning labels; other designs can be customised.
Resistant to chemicals, extreme temperatures and UV rays.
Key retention: the key cannot be removed while the shackle is open.
Laser marking and logo engraving available on request.

Combination records
It is important that every employee at a facility has a unique padlock key, so that duplicate keys do not compromise the lockout programme. On request, different combinations and numbering are used for each order. In addition, the combination of each key is recorded, so identical keys can be replaced whenever needed.

Master key system
System diagram: keyed different (KD); keyed alike (KA), group 1 and group 2; master key + keyed different (KDMK); master key + keyed alike (KAMK); grand master key (GMK).
Keyed different (KD): each padlock has a different key; 1 key is supplied per padlock. Up to 50,000 individual combinations available.
Keyed alike (KA): all padlocks in the same group share a key; 1 key opens every padlock in the group.
Master key + keyed different (KDMK): each padlock has a different key, with 1 key per padlock. A master key also opens all of those padlocks.
Master key + keyed alike (KAMK): all padlocks in the same group share a key. A master key also opens all keyed-alike groups.
Grand master key (GMK): each padlock in a group has a different key. A grand master key opens all KDMK groups.
