TL 01 Thumb Latch

Manufacturer: SRS Hardware

(2 customer reviews)

SRS’s TL 01 sash lock is an updated version of the old Babcock Patent Barrel Lock. These clever locks are used in single hung window applications where no balance system is present. If you have an old home, you’ve experienced the vexing issue of how to hold the lower (operable) sash open. Owners have come up with myriad ways to prop their lower sash open, from sticks to paperbacks (which inevitably end up falling out of the window and into the shrubs, never to be seen again). Our TL 01 lock solves this problem forever! They are easily retrofitted into existing windows (requiring the removal of one sash stop and the lower sash) are unobtrusive and permanent.
Note: use 3/4″ Forstner or Multispur bit to drill the hole into the jamb. As ever with tight fitting hardware or screws, a bit of Bowling Wax the threads is good practice and will ease installation.

Only the small “pushbutton” remains visible and the locks are available with 4 pushbutton finishes: lacquered brass, oil rubbed bronze, satin nickel and polished nickel.

Sold individually and boxes of 20.

  1. Farmer Mike, Connecticut (verified owner)

    The double hung windows on my 1740 farmhouse use old sash locks, which may be antique Babcock locks. Several have broken thumb levers, so I decided to replace the broken locks with the SRS TL 01 lock. The replacement process was easy, requiring a 3/4″ mounting hole, new window sash slot, and new sash stop slot. Because my windows are very old and fit loosely, the size of the catch pin on the TL 01 is a bit small to securely hold the window. The new lock works, but if the window shifts a bit, it may fall off the latch. (This is why I only gave it four stars.)

    I was impressed by the quality of the TL 01 latch and its smooth spring action. Support from SRS was quick and very helpful. This is a great product, backed by great support. Thanks!

    While renovating our old house we were delighted to find online SRS Hardware’s TL 01 reproduction thumb latch to match our existing late 19th century Babcock Lock window sash lock hardware. We ordered them in oil rubbed bronze. They were shipped immediately and arrived quickly. They are beautifully made, installed easily, and work perfectly. Thank you Justin!

"Thanks for your expedient and attentive shipping of the weights.  Thanks, also for choosing a courteous and thoughtful carrier.  They worked with me to find a convenient delivery date and the driver was courteous in asking if I wanted delivery in the alley (which is more convenient) even before I had time to raise the issue.
