                    COMPX REPORTS FOURTH QUARTER 2005 RESULTS

Dallas,  TEXAS ...  March 16, 2006 ...  CompX  International  Inc.  (NYSE:  CIX)
announced  today sales of $46.7 million for the fourth  quarter of 2005 compared
to $46.6 million in the same period of 2004.  Operating  income was $5.5 million
in the fourth  quarter of 2005  compared  to $3.0  million in the same period of
2004. Net sales for the year ended December 31, 2005 increased to $186.3 million
compared to $182.6  million in the  previous  year.  Operating  income was $19.1
million for the year ended  December 31, 2005  compared to $15.4 million for the
comparable  period of 2004. For the year, net sales  comparisons were positively
impacted by sales volume  associated with the acquisition of a small  components
business  in August  2005,  the  positive  effect of  fluctuations  in  currency
exchange  rates  (which  increased  sales by $1.5  million  in the  year-to-date
period) and increases in selling prices for certain products across all segments
to recover volatile raw material  prices.  These positive effects were partially
offset by sales  volume  decreases  in  certain  products  resulting  from Asian
competition.  Operating  income  comparisons  were  primarily  impacted  by  the
favorable impact of continued  reductions in  manufacturing,  fixed overhead and
other  overhead  costs,  partially  offset by a negative  impact  from  currency
exchange rates (which  decreased  operating  income by $2.3 million in 2005) and
higher raw material costs.

Income from continuing operations improved to $2.4 million, or $0.16 per diluted
share, in the fourth quarter of 2005, up from $1.4 million, or $0.09 per diluted
share,  in the same period in 2004.  Income from  continuing  operations for the
year ended December 31, 2005 was $900,000,  or $0.06 per diluted share, compared
to $9.5 million,  or $0.63 per diluted share in 2004.  The full year 2005 amount
was negatively impacted by a change in the Company's expectation relating to the
repatriation of non-U.S.  earnings that resulted in the Company incurring a one-
time   non-cash   income  tax  charge  during  the  third  quarter  of  2005  of
approximately $9.0 million ($0.59 per diluted share).

"In  2005 we  continued  to make  progress  in  improving  our  margins  through
increased volumes on more profitable  products and a focus on continuing efforts
that  emphasize  cost control and  production  efficiency,"  commented  David A.
Bowers, President & CEO. "Additionally,  we made progress with new opportunities
for growth and  diversification  with the  completion  of one  relatively  small
acquisition in August. Our strong liquidity and financial position will allow us
to continue to explore additional growth opportunities."

CompX is a leading  manufacturer  of  precision  ball bearing  slides,  security
products  and  ergonomic  computer  support  systems.  It  operates  from  eight

Statements in this release relating to matters that are not historical facts are
forward-looking  statements based upon management's belief and assumptions using
currently  available  information.  Although  CompX  believes  the  expectations
reflected in such forward-looking  statements are reasonable, it cannot give any
assurances that these expectations will prove to be correct. Such statements, by
their  nature,   involve   substantial  risks  and   uncertainties   that  could
significantly  impact expected  results,  and actual future results could differ
materially from those described in such forward-looking statements.  While it is
not  possible to identify all  factors,  CompX  continues to face many risks and
uncertainties.  Among the factors  that could  cause  actual  future  results to
differ  materially  include,  but are  not  limited  to,  general  economic  and
political conditions,  demand for office furniture,  service industry employment
levels,  competitive  products  and prices,  fluctuations  in currency  exchange
rates, the introduction of trade barriers, potential difficulties in integrating
completed  acquisitions,  the  timing  and amount of future  cost  savings  from
restructuring  actions,  the  ability to sustain or  increase  operating  income
improvement  resulting from cost control initiatives,  uncertainties  associated
with new  product  development  and other  risks and  uncertainties  detailed in
CompX's Securities and Exchange Commission filings.  Should one or more of these
risks materialize (or the consequences of such a development  worsen), or should
the  underlying  assumptions  prove  incorrect,   actual  results  could  differ
materially  from those  forecast or expected.  CompX  disclaims any intention or
obligation to publicly update or revise such  statements  whether as a result of
new information, future events or otherwise.
