A sliding door lock It is not chosen only for aesthetics. It changes completely depending on door type (recessed, on wall, aluminum, glass), use (bathroom, bedroom, cupboard, office, terrace) y security level what you need. As locksmith 24/7 In Tarragona, I have seen sliding doors that do not close simply mismatch, vulnerable exteriors due to lack of hook/anti-lift and bathrooms that gain privacy with a magnetic latch well assembled. Here is my direct and practical guide (no prices; always prior written estimate).

Types of sliding locks: magnetic, hook, with cylinder and for glass

1) Magnetic latch/knob (interior)

Ideal for bathrooms and bedrooms. Soft close, no hits, and avoid friction.
Versions with condemn (privacy) and exterior emergency visor.
Handles sausages (nails) so that the sheet is hidden in the partition.

2) hook latch (hook bolt)

Recommended for exterior sliding (terrace/window) and areas with risk of leverage.
He hook hugs the striker and makes leverage difficult. Can be combined with Multipunto.

3) Cylinder lock (key)

To workshops, interior storage rooms or rooms where you require keys on one or both sides.
Compatibilities: europrofile cylinder u oval, and possibility of patented key with property card.

4) glass slide (without drilling or with patch lock)

systems clamp/patch that hold the glass and add latch/key.
Options with condemn bathroom and soft close; important the accessories: guides, bumpers and soft‑close.

Experience: on a bathroom slide that “bounced”, the change to magnetic latch + striker adjustment left closure silent and reliable.

How to choose according to use: bathroom, bedroom, office, closet and exterior/terrace

Bathroom / bedroom (interior)

Magnetic with condemnation. Prioritize softness, privacy and an emergency viewer.
Handles sausages (nails) y flush closure for pocket doors.

Office / rooms with restricted access

Cylinder lock (key) y, if there are multiple doors, plan of equalization.
Rate patented key (property card) to control copies.

Wardrobes / utility rooms

Solution simple: latch or hitch closure; avoid protrusions that rub against the guide.

Terrace / exterior

Hook (hook) + system antieleva; if there is exposure, duck Multipunto or additional closures.
Review pranks and adjustments so that the blade does not “dance”.

Experience: in a window that was opened with a lever, I installed hook + antieleva and car adjustment. Since then, zero successful attempts.

Key measurements before buying: box, thickness and centers (checklist)

Door thickness (mm): determines the type of box and hardware.
Box width and height: especially in built-in (pocket) so as not to invade the septum.
Centers: distance between square (handle/condemnation) and the front edge.
Front type (straight/curved) y finish (stainless steel, brass, negro).
Handle Compatibility (inlaid nails, with or without pull handle).
Keeper: must align with wall or frame with tolerance for expansion.
Accessories: soft‑close, bumpers, brushes, antieleva.

field trick: If the door rubs or the centered hook does not fit, don't force. Adjust guide and strike plate before blaming the lock.

Security on exterior sliding: hook, anti-lift and supplementary closures

Hook (hook): increases lever resistance; better if the striker is reinforced.
Antieleva: prevents them from lifting the blade to dislodge it. Essential in aluminum/windows.
Multipoint: several distributed hooks to make attacks difficult.
Glass: usa patch locks with certified hardware and closes the perimeter (stops/adjustments).

Experience: when they call me for “easy” slides, my recipe is hook + antieleva y readjustment of carriages/stops. It works.

Installation: what you can do and when to call a locksmith 24/7 In Tarragona

DIY (you do it) and:

you know how to measure thickness/centers and you have a drill/screwdriver,
the door run aligned and you're just going to change the forehead of the lock or add nails.

In my service in Tarragona I prioritize opening without damage and shipping prior written estimate before intervening. So there are no surprises.

Common problems (mismatch, clearances, roces) and how do I solve them in the field?

Sheet imbalance: readjustment of carriages/bearings and top guide leveling.
Hook that does not fit: mover keeper millimetrically until centered; check limits.
Rubbing against the septum in built-in: check plumb and clearances; adjust front or choose narrower case.
noisy closing: go to magnetic and add soft‑close.
Poor outdoor security: add antieleva y, we proceed, Multipunto.

Experience: emergency opening in blocked bathroom. I didn't break the blade: I agreed for him forehead, I released the bolt and set the sentence. Perfect closure.
