✅ Fits
Suitable for general English longcase (grandfather) clocks using the standard rectangular chop-and-crutch suspension arrangement, where the block runs in a slotted crutch. Sold as a single block — a good option if you already have a working spring or matching block and just need to replace a damaged top or bottom chop. Not matched to any specific named movement or manufacturer; compare your existing block's outer size, hole-to-pin distance and thread against this one before buying.
⚠️ Please check the thread on the bored end has not been measured with a gauge — English longcase blocks commonly use several similar but non-interchangeable BA-style threads, so confirm pitch and diameter against your own suspension assembly before fitting.
