these low Profile end returns have been fabricated in lieu of end caps or end blocks. they are crown returns for 2 5/8 crown molding . Each transition is approx 2 1/4” from center to end as depicted in photo! I also installed a guide tab to make transition easier! purchase price is for 2 low Profile Transitions (1 left, 1 right) these have also been primed and painted two coats with Benjamin Moore super white semi-gloss paint! block in photo is made to transition with standard 4 5/8 moulding! If you need more/less or wish to combine one with any over my other listings or need different sizes just send me a message and I will create a listing for you!
