Borg BLS275000LH / BLS275000RH 28mm Latch - Left or Right Hand - Suits 5000 Series - Satin Chrome

The Borg BLS275000LH / BLS275000RH is the 28mm short-backset mortice latch for Borg BL5000 Series digital locks, made for aluminium shopfront doors and other narrow-stile applications. It is a latch-only replacement, supplied as two separate handed parts - a left-hand latch (BLS275000LH) and a right-hand latch (BLS275000RH). Order the hand that matches your door.

It has a 28mm backset, it runs on an 8mm square spindle, and although it is supplied handed, a locksmith or a competent handy person can change the hand on the bench.

Which 28mm Latch - 5000 Series or 2000 Series?

We stock two 28mm short-backset latches and they look almost identical in a photograph - same 28mm backset, same slim face plate, same satin chrome. The difference is the drive, and it is on the back of the latch where the spindle passes through. This one, for the 5000 Series, takes an 8mm square spindle. The 2000 and 4000 Series latch is driven by a tail piece. Work out which lock you have before you order.

The two are not interchangeable. The drives are different, so a 2000 or 4000 Series latch will not take the 8mm square spindle of a 5000 Series lock. Match the latch to the lock, not just to the backset - and if you are not sure which Borg series you have, send us a photo of the keypad and we will tell you.

Compatible Locks

This 28mm latch fits Borg BL5000 Series locks in aluminium and narrow-stile door preparations. These lock pages list it for narrow stiles - confirm the fit with us before ordering. For standard timber-door backsets, the 60mm and 70mm 5000 Series latches apply. The 2000 Series equivalents are the BLS272000LH and BLS272000RH, which run on a different drive.

Frequently Asked Questions

Does it suit all Borg digital locks?
No - it is designed for the Borg BL5000 Series. It is not for the 2000 / 4000 Series keypads.
Will the 2000 Series 28mm latch fit a 5000 Series lock?
No. Both are 28mm latches and they look alike, but the 2000 and 4000 Series latch is driven by a tail piece and this one takes an 8mm square spindle. The two drives side by side shows the difference.
Does this include the keypad or lock body?
No - it is the mortice latch that fits inside a Borg BL5000 Series lock. Pair it with your existing lock body and keypad.
Which hand do I order?
Order the left-hand latch (BLS275000LH) for a left-hand door or the right-hand latch (BLS275000RH) for a right-hand door. If you are unsure which way your door is handed, see understanding door handing in Australia. Getting it wrong is not the end of the world - the hand can be changed on the bench.

Additional Information

Short backset for aluminium. 28mm backset latches are commonly needed for aluminium framing systems where a standard 60mm backset will not fit.
Order the correct hand. This listing covers both handed latches - the left-hand BLS275000LH and the right-hand BLS275000RH. They are separate parts, not one latch that works either way out of the box, so check your door handing and tell us which hand you need when you order.
Changing the hand on site. A wrong-hand latch is not a wasted latch. A locksmith or a competent handy person can change the hand with a screwdriver, following Borg's Ali-Latch handing guide: out with the four screws, off with the back plate, out with the two coil springs, the latch bolt and the anti-thrust pin, then the pin is driven out of the latch bolt, the latch tail piece is flipped to the other side and the latch goes back together. It is a bench job with the latch out of the door rather than something done in the doorway, so it suits a workshop or the back of the van.
Steel gates. On a steel gate with a narrow stile, the other route is a weld-on lock box at the standard 60mm backset - the BDS LB22 lock box for Borg 5000 Series locks.
