Find string with hyphen usng t-sql

Hi,

I have a requirements to find string with a hyphen like -RTR but the codes below there are some string that did not give the result specially the 5th records on my sample data. May i ask your assistance on how to make this using t-sql. thank you in advance.

CASE WHEN sal.NAME like '%-RTR%' THEN LEFT(sal.NAME, charindex('-RTR', sal.NAME))+'RTR' ELSE '' END as SKU

--DDL
create table #sample
(item nvarchar(50))
insert into #sample(item) values('HOT3053-RTR/2937-RTR Motorola DRDRZRMX Housing Frame')
insert into #sample(item) values('HOT3053-RTR Motorola DRDRZRMX Housing Frame') 
insert into #sample(item) values('DAM1615-RTR  LP - LCM Assembly') 
insert into #sample(item) values('Scraped Plastic kit HOT2937-RTR  DROIDRAZOR2 Housing Frame')
insert into #sample(item) values('INCREDIBLE00193 HHC1035-RTR')
